Tunable laser-diode-pumped Nd:YAG microcrystal lasers at 1.4 /spl mu/m

摘要

TEM/sub 00/ laser operation of a monolithic Nd:YAG crystal laser has been achieved on three transitions at 1.414 /spl mu/m, 1.444 /spl mu/m and at 1.431 /spl mu/m with laser diode pumping at 808 nm. The laser threshold was 1.5 W and the maximum output power 50 mW. The gain linewidths at 1.414 /spl mu/m and 1.444 /spl mu/m were determined by means of temperature tuning the microcrystal lasers. Calculations for designing tunable single frequency microcrystal lasers have been performed.
