摘要	A single longitudinal mode frequency-converted solid-state laser includes an optical pumping source 10 a coupled resonant cavity 40 having a first resonant cavity 42 and a second resonant cavity 44 sharing a common partially reflecting mirror 13, a solid-state laser medium 22 disposed within the first resonant cavity and pumped by the pumping source 10, and an optical wavelength converting means 24 (e.g. a frequency doubler) within said second resonant cavity. The laser medium 22 generates a first laser radiation at a first wavelength which is converted by the wavelength converting means 24 into a second laser radiation at a second wavelength. A temperature controlling means 31 controls the temperatures of the first and the second resonant cavities 42, 44 and of the optical pumping source 10.; The optical path lengths of the first resonant cavity 42 and the second resonant cavity 44 are selected such that only one longitudinal mode of the coupled resonant cavity is within the gain bandwidth of the laser medium. Control of optical path lengths is achieved by the temperature controlling means 31 in order to stabilise the output of the laser. The temperature controlling means 31 may also allow the laser to be operated selectively in single mode and multiple mode operation.
其他摘要	单纵模频率转换固态激光器包括光泵浦源10，耦合谐振腔40，其具有第一谐振腔42和共用共同部分反射镜13的第二谐振腔44，设置有固态激光介质22在第一谐振腔内并由泵浦源10泵浦，以及在所述第二谐振腔内的光波长转换装置24（例如倍频器）。激光介质22产生第一波长的第一激光辐射，其由波长转换装置24转换成第二波长的第二激光辐射。温度控制装置31控制第一和第二谐振腔42,44和光泵浦源10的温度。选择第一谐振腔42和第二谐振腔44的光程长度，使得耦合谐振腔的仅一个纵向模式在激光介质的增益带宽内。通过温度控制装置31实现光程长度的控制，以稳定激光器的输出。温度控制装置31还可以允许激光器在单模和多模操作中选择性地操作。
