Fluorescence lifetime quenching of first test samples was analyzed and attributed to the hydroxide OH concentration in the host material.

Applying a sophisticated glass manufacturing process, OH concentrations could be lowered by up to two orders of magnitude, rising the lifetime and the quantum efficiency for samples doped with more than 6.

First laser experiments showed a broad tuning range of about 60 nm, which is superior to Yb:CaF 2 and Yb:FP-glass in the same setup.

Furthermore, measurements of the laser induced damage threshold LIDT for different coating techniques on doped substrates revealed the appropriateness of the materials for short pulse high-energy laser amplification.

Proceedings Article 13 March Progress in high-energy-class diode laser pump sources. Crump , C. Frevert , Frank Bugge , S.

Knigge , G. Erbert , G. Tränkle , A. Pietrzak , R. Hein , T. A new generation of diode-pumped high-energy-class solid-state laser facilities is in development that generate multijoule pulse energies at around 10 Hz.

Currently deployed quasi-continuous-wave QCW diode lasers deliver average inpulse pump powers of around W per bar. Increased power-per-bar helps to reduce the system size, complexity and cost per Joule and the increased pump brilliance also enables more efficient operation of the solid state laser itself.

We review here the status of these high-energy-class pump sources, showing how the highest powers are enabled by using long resonators 4…6 mm for improved cooling and robustly passivated output facets for high reliability.

Results are presented for prototype passively-cooled single bar assemblies and monolithic stacked QCW arrays. Proceedings Article 31 October Mariastefania De Vido , P.

YAG as the host medium offers good thermo-mechanical and thermo-optical properties and, if it is used in ceramic form, it can be produced in large sizes with laser-grade optical properties.

Large sized, laser-grade gain media are pivotal for the development of high energy kJ-class laser systems. Much effort has been devoted to the development of advanced polishing and coating techniques in order to produce optical materials able to withstand high fluence levels at different environmental conditions.

Performance of IBS coatings improves as substrate roughness decreases, whereas performance of IAD coatings improves as substrate roughness increases.

No clear correlation has been observed between LIDT values and temperature or pressure. However, an inspection of damage sites allowed to conclude that both temperature and pressure have an impact on damage morphology.

Proceedings Article 7 May To obtain the emission cross-sections two theoretical approaches were used. The first is the McCumber or reciprocity method RM which is based on the absorption spectra.

The second is the Fuchtbauer-Ladenburg FL method using fluorescence spectra. From the results of cross-sections one can expect significant impact on laser performance on these materials especially in the case of high energy class diode pumped solid state lasers.

Diode-pumped, cryogenically cooled, femtosecond burst mode laser. We present a novel approach for the construction of a high energy, high power burst mode laser system, based on diode pumped cryogenically cooled Yb:CaF 2.

The system consists of a frontend producing pulses of fs duration with 1 MHz. Bursts of subsequent pulses are cut from the continuous train by an electro optical modulator.

Afterwards the duration of the individual pulses is stretched to 50 ps. The amplifier system consists of two amplifiers.

Both amplifiers utilize mirror based relay imaging schemes to allow for a sufficient number of extraction passes for achieving efficient energy extraction.

The goal parameters of the system are to achieve a total energy of 5J per burst with a repetition rate of 10Hz. Amplification results for the first of two amplifiers are demonstrated.

Single pulse energies of up to 7. To achieve a constant energy from pulse to pulse during the burst we present a technique based on the modulation of the laser diode current during one pulse.

Keppler , C. Wandt , M. Hornung , R. Bödefeld , A. Kessler , A. Sävert , M. Hellwing , F. Schorcht , J. Hein , M. Advanced high intensity laser matter interaction experiments always call for optimized laser performance.

In order to further enhance the POLARIS laser system, operational at the University of Jena and the Helmholtz-Institute Jena, in particular its energy, bandwidth and focusability, new amplifier technologies have been developed and are reported here.

Additionally, existing sections were considerably improved. A new multi-pass amplification stage, which is able to replace two currently used ones, was developed in close collaboration with the MPQ Garching.

The new basic elements of this amplifier are well homogenized pump modules and the application of a successive imaging principle.

By operating the amplifier under vacuum conditions a top hat beam profile with an output energy of up to 1. The already implemented POLARIS amplifier A4 was further improved by adapting an advanced method for the homogenization of the multi-spot composed pump profile.

The new method comprises a computer-based evolutionary algorithm which optimizes the position of the different spots regarding its individual size, shape and intensity.

Proceedings Article 18 February HiLASE cryogenically-cooled diode-pumped laser prototype for inertial fusion energy. Results of detailed energetics and thermo-optical modeling confirm the viability of cryogenic helium-gas cooling approach to drastically reduce thermally-induced distortions in the laser slabs.

In addition, a comparison of spectral measurements from laser-diode stacks and Yb:YAG crystals validates the feasibility of highly efficient diode-pumped solid-state lasers at cryogenic temperatures.

The optical quality and the laser damage threshold are influenced by the purity and the real structure of the crystal. Both properties strongly depend on raw material quality and growth conditions.

Production of pure CaF 2 single crystals and their characterization are described. The advantage of higher volume is a better homogeneity of the dopant concentration and the diffractive index in the crystal.

Critical mechanical properties especially of the doped fluoride have to be taken into account. The growth process has to be adopted carefully to avoid stress, cracks and other crystal defects.

Data of refractive index homogeneity and stress birefringence are presented. A comparison of doped and undoped crystals is made and an outlook for further improvement is given.

The segregation coefficient of the dopant which is important to be near to one is reported. Differences between top and bottom of the crystal are shown.

Results of the real structure evaluation are presented. The most critical feature for high energy applications which are strength and concentration of small angle grain boundaries are compared with that of undoped crystals.

Körner , J. Kahle , H. Liebetrau , M. Lenski , M. Kaluza , M. Loeser , M. For laser performance simulations, optical properties of applied active materials have to be exactly known.

The temperature of the samples was aligned in steps of 20 K between K and room temperature with a liquid nitrogen driven cryostat. Absorption spectra were obtained with a fiber coupled white light source and fluorescence spectra by excitation with a fiber coupled 10W laser diode at nm.

All spectral measurements were performed with a scanning spectrum analyzer, providing a spectral resolution down to 0. By applying the McCumber relation in combination with the Fuchtbauer-Ladenburg method, we were able to obtain a valid emission cross section over the whole range of interest from the measured data.

High-efficiency cyrogenic-cooled diode-pumped amplifier with relay imaging for nanosecond pulses. Siebold , M. The temperature of these materials was adjusted arbitrarily between K and K, while heat removal was realized by transverse cooling.

In order to obtain a good beam profile throughout the amplification process, we used an all-mirror based relay imaging setup consisting of a telescope accomplishing a 4f-imaging with a plane mirror in each image plane.

The amplification beam is then coupled into the cavity and doing several round trips wandering over the surface of the spherical mirrors. Hence the laser material is placed in one of the image planes, the beam quality of the amplifier was ruled by the intensity profile of the pumping laser diodes consisting of two stacks with 2.

Due to the given damage threshold fluence, the output energy of the amplifier was limited to about 1J at a beam diameter of 4. The seed pulses with a duration of 6 ns were generated in a Yb:FPglass cavity dumped oscillator with further amplification up to the mJ level by a room temperature Yb:YAG multi pass amplifier.
