Abstract

High-quality monoclinic planar waveguide crystals of Tm-doped KY(WO4)2 codoped with Gd3+ and Lu3+ were grown by liquid-phase epitaxy. For the first time, planar waveguide lasing was demonstrated in a monolithic cavity in the 2 µm spectral range. The laser was operated in the Q-switched mode using a Cr2+:ZnSe crystal as saturable absorber and in the continuous-wave regimes. The Q-switched planar waveguide laser delivered pulse energies up to 120 nJ at a repetition rate of 7 kHz.

摘要

通过液相外延生长出了高质量的掺铥钆镥共掺的单斜晶系平面波导晶体KY(WO4)2。首次在2微米光谱范围内的单片腔中实现了平面波导激光发射。该激光器使用Cr2+:ZnSe晶体作为可饱和吸收体，以调Q模式和连续波模式运行。调Q平面波导激光器在7千赫兹的重复频率下输出的脉冲能量高达120纳焦。
