  • Nd:YAG 200-W average-power oscillator-Amplifier system with stimulated-Brillouin-scattering phase conjugation and depolarization compensation
    Journal of the Optical Society of America B, 1997
    Co-Authors: S. Seidel, N. Kugler
    Abstract:

    A flash-lamp-pumped, Q-switched Nd:YAG oscillator-Amplifier system with an average output power of 215 W and a beam–parameter product of less than 1 mm mrad is developed. The system operates with a 100-Hz repetition rate and emits a burst of 20 Q-switched pulses during each flash-lamp pulse with pulse durations of 100 ns. The high beam quality of the amplified beam is realized by a double-pass configuration of the Amplifiers with a phase conjugating stimulated-Brillouin-scattering cell. Additionally, the thermally induced birefringence of the Amplifiers is compensated by a 90° rotator and an optical image-relay system between two Identical Amplifier rods.

  • High-average-power frequency conversion with phase-conjugated laser systems
    High-Power Lasers: Gas and Solid State Lasers, 1996
    Co-Authors: S. Seidel, Guido Mann
    Abstract:

    High average powers at 532 nm are of great interest for material processing applications because the absorption of metals and other materials increases with shorter wavelength. As the fundamental laser source we developed a Q-switched Nd:YAG oscillator-Amplifier system with an average output power of 215 watts and a beam parameter product of less than 1 mm*mrad. The system operates with 100 Hz repetition rate and emits a burst of twenty Q-switch pulses during each flash-lamp pulse. The pulse duration of a single pulse increases from 100 to 200 nanoseconds with increasing pumping power. The high beam quality of the amplified beam is realized by a double-pass configuration of the Amplifier with a phase conjugating SBS-cell. Additionally the thermally induced birefringence of the Amplifiers is compensated for by a 90 degree-rotator between two Identical Amplifier rods. An output power of 164 W is frequency doubled in a KTP-crystal to 82 Watt average output power in the green which corresponds to 50% of doubling efficiency.

  • Thin-disk ring Amplifier for high pulse energy.
    Optics express, 2016
    Co-Authors: Robert Jung, J. Tümmler, Thomas Nubbemeyer, Ingo Will
    Abstract:

    A CPA laser system for high pulse energy at high average power has been developed. The system is based on Yb:YAG thin-disk technology. It provides two laser beams with more than 500 mJ pulse energy each at 100 Hz repetition rate and 2 ps pulse duration. The system consists of a common oscillator, a grating stretcher and compressor and two Identical Amplifier chains that are both equipped with a regenerative Amplifier and a ring Amplifier. The compressor supports an individual alignment of the dispersion for the two laser channels.

  • Design of high-energy-class cryogenically cooled Yb3+∶YAG multislab laser system with low wavefront distortion
    Optical Engineering, 2013
    Co-Authors: Martin Divoky, Pawel Sikocinski, Jan Pilar, Antonio Lucianetti, M. Sawicka, Ondrej Slezak, Tomas Mocek
    Abstract:

    Detailed modeling results of 100 J class laser systems with respect to the output energy, beam propagation, nonlinear phase accumu- lation, wavefront aberrations, and adaptive optics performance obtained in MIRO and MATLAB codes are presented here. The laser system is based on a cryogenically cooled Yb 3þ ∶YAG multislab Amplifier with two Identical Amplifier heads and operates at 10 Hz repetition rate with an average power above 1 kW. © 2013 Society of Photo-Optical Instrumentation Engineers

  • Comparative design study of 100 J cryogenically cooled Yb:YAG multi-slab Amplifiers operating at 10 Hz
    Solid State Lasers XXI: Technology and Devices, 2012
    Co-Authors: Pawel Sikocinski, Martin Divoky, Antonio Lucianetti, M. Sawicka, Jakub Novák, Bedrich Rus, Tomas Mocek
    Abstract:

    We present a comparison of two conceptual layouts of 100 J class laser systems for HiLASE and ELI Beamlines projects with respect to the output energy, beam propagation and system performance obtained from MIRO code. Both systems are based on cryogenically cooled Yb:YAG multi-slabs Amplifiers technology and operate at 10 Hz repetition rate with average power above 1 kW. First concept of the laser system consists of separate 10 J preAmplifier and 100 J power Amplifiers, while the second consists of a main Amplifier with two Identical Amplifier heads delivering 100 J.
