Beschreibung
Bivoj laser system is located at Hilase center near Prague, Czechia. While built around DiPOLE technology (cryogenically cooled Yb:YAG multi-slab laser system), it has been upgraded to reach higher output energies up to 1.5 KW of average power (150 J / 10 Hz) and the problem of so called depolarization has been successfully addressed, which led to reduction of depolarization losses from ~30% to less than 4%. Such improvement enabled efficient use of its output beam as a source for harmonic conversion stages which demonstrated stable operation at close to 1 kW (95 J / 10 Hz) @515 nm and 0.5kW (50 J / 10 Hz) @343 nm. Such laser system could serve as a suitable pump source for ultra-fast lasers envisioned for laser particle accelerators. Possibilities for future development of such pump lasers will be discussed.
