摘要

微芯片激光器中由泵浦引起的折射率变化可以对其频率进行调谐、调制和控制。研究了两种808 nm泵浦的微芯片激光器结构(Nd:YVO/sub 4/和Nd:YAG @ 1064 nm)。微芯片激光器的泵浦诱导可调谐性在数十MHz/mW的水平上。仅施加/spl + /5%的泵浦功率变化，两个微芯片激光器之间的偏移频率可以稳定数小时。利用这种控制技术，我们将激光频率的长期稳定性提高了三个数量级。

Opto-thermal frequency control of diode pumped microlasers

The pump-induced changes of refractive index in the microchip laser allow tuning, modulation and control its frequency. We investigated two configurations of microchip lasers (Nd:YVO/sub 4/ and Nd:YAG @ 1064 nm) with 808 nm pumping. The pump-induced tunability of microchip lasers was found to be on the level of tens MHz/mW. The offset frequency between two microchip lasers could be stabilised for hours applying only /spl plusmn/5%-changes of pumping power. Using this technique of control, we improved long term laser frequency stability up to three orders.
