摘要： The present invention relates to a stable solid-state Raman laser, the solid-state Raman laser including a resonator cavity defined by at least two reflectors, a laser material located in the resonator cavity and capable of generating a cavity laser beam which propagates within the resonator cavity, a solid Raman medium located in the resonator cavity for shifting the frequency of the cavity laser beam to produce a Raman laser beam which propagates within the resonator cavity; and an output coupler for coupling and outputting the Raman laser beam from the resonator cavity, wherein at least one parameter selected from the group consisting of the position of the laser material relative to the position of the Raman medium in the cavity, the length of the cavity and the curvature of at least one of the reflectors, is selected such that changes in the focal lengths of both the laser material and the Raman medium as a result of thermal effects in the laser material and the Raman medium during operation of the laser do not substantially cause instability in the power of the output Raman laser beam. A method of maintaining stable operation of a solid state Raman laser is also described.
