Yb:YAG/Cr:YAG Composite Crystal with External and Microchip Resonator

Popis výsledku v původním jazyce

A compact diode pumped Q-switched lasers, operating at wavelength 1031 nm, were based on the composite crystal Yb:YAG/Cr:YAG. This composite crystal (diameter 3mm) consisted of diffusion bounded 3mm long Yb:YAG (10 at.% Yb/Y) and 1.6mm long Cr:YAG crystal (initial transmission 85% @ 1031 nm). External resonator allowing to tune generated Q-switched pulse parameters or microchip configuration offering the shortest pulses and highest peak power were tested for this device. For longitudinal pumping of Yb:YAG gain medium, fibre coupled (core diameter 200 um, NA= 0.22) laser diode, operating at wavelength 968 nm, was used. In the first case, Yb:YAG/Cr:YAG composite crystal was AR-coated and placed inside the 150mm long semihemispherical resonator consistedof a at pumping mirror (HR @ 1.01- 1.09 um, HT @ 0.97 um) and curved output coupler (r = 150mm) with reflectivity 70% @ 1031 nm. Generated pulses with the peak power 23kW were 17 ns long (FWHM). The highest generated pulse energy was 0.38
