英文摘要	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.
