Yb:YAG/Cr:YAG Microchip Laser Output Energy Optimization

Popis výsledku v původním jazyce

The influence of pumping beam diameter on output of the room-Temperature operated Q-switched longitudinally diode-pumped Yb:YAG microchip laser was investigated. The tested microchip laser was based on monolith crystal (diameter 3mm) which combines in one piece an active laser part (Yb:YAG crystal, 10 at.% Yb/Y, 3mm long) and saturable absorber (Cr:YAG crystal, 1.36mm long, initial transmission 90% @ 1031 nm). The microchip resonator consisted of dielectric mirrors directly deposited on the monolith surfaces. The pump mirror was placed on the Yb:YAG part. The output coupler with reflection 55% for the generated wavelength was placed on the Cr3+-doped part. For longitudinal pumping, fibre coupled laser diode was used. The diode was operating in pulsed regime. Three various pumping optics offering pumping beam radius 0.21, 0.27, and 0.32 mm were used. The wavelength of microchip laser emission was 1031 nm. The pumping beam radius did not significantly inuenced the pulse duration which was 1.5 ns (FWHM) in all three cases. The highest generated single Q-switched pulse energy (1.08 mJ) was obtained for pumping beam radius 0.27mm for maximum pumping. The corresponding peak power was 0.72MW.
