Detailed Technology Description

Stable solid-state Raman laser, the solid-state Raman laser including:
(a) a resonator cavity defined by at least two reflectors,
(b) a laser material located in the resonator cavity and capable of generating a cavity laser beam which propagates within the resonator cavity,
(c) 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 (d) an output coupler for coupling and outputting the Rama laser beam from the resonator cavity, wherein at least one parameter selected from the group consisting of (i) the position of the laser material relative to the position of the Raman medium in the cavity, (ii) the length of the cavity and (iii) 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 during operation of the laser do not substantially cause instability in the power of the output Raman laser beam.
