Abstract:
An investigation was made of a high-power pulsed high-pressure laser utilizing 4d[1/2]01–5p[3/2]2(λ=2.52μ) and 6p[1/2]1–6s[3/2]02(λ=3.07μ) transitions in Kr atoms pumped by a fastelectron beam. When the volume of the active region was 10 liters and the pressure was 3.5 atm, the output energy of the laser reached 1.2 J and the efficiency was ~1%.
