Abstract : A tunable solid state laser produces a laser emission at one or more wavelengths simultaneously. The tunable solid state laser includes a laser resonator defined by an output coupler reflective element, two fold mirrors, and one or more high reflectivity end elements to form a reflective path in a laser resonator cavity there between with a laser crystal disposed in the laser resonator cavity. A means for optically exciting the laser crystal is appropriately disposed for end pumping the laser crystal to produce a laser emission in a predetermined range of wavelengths. A wavelength dispersing element such as a prism is disposed in the laser resonator cavity between one of the fold mirrors and the high reflectivity end elements for tuning the laser emission at one or more of the desired wavelengths in the predetermined range of wavelengths, the dispersing element being transparent to the laser emission over the predetermined range of wavelengths.
