In this work we present a novel method for depolarization compensation based on spatially variable wave plate. Thermally induced depolarization losses were reduced from 14.3% to 1.3% and bifocusing eliminated in a double-pass Yb:YAG amplifier.

A subpicosecond laser system featuring a fiber chirped pulse amplification-based seed laser and a double-pass end-pumped Yb:YAG crystal power amplifier was investigated. The key novelty of the system was the application of depolarization compensation

Chirped pulse amplification (CPA) technique was realized in Nd:YVO4 and Nd:YAG amplifiers. The front-end of the system consists of an Yb-doped fiber-optic master oscillator and a chirped fiber Bragg grating stretcher with a chain of Nd-based solid-st

We report on the developed front-end/pump system for optical parametric chirped pulse amplifiers. The system is based on a dual output fiber oscillator/power amplifier which seeds and assures all-optical synchronization of femtosecond Yb and picoseco

We analyse the concept of collinearly pumped active medium consisting of multiple thin disks (multi-disk configuration). The multiple disk design is attractive for fabrication of mid- and high-output power laser systems with a good spatial beam quali

A laser amplifier set-up that can be used as an effective pump source for an optical parametric chirped pulse amplification system is presented in this paper. 1-mJ 48-ps seed pulses were amplified to the energy of 80 mJ. The system operated at 1 kHz
