Abstract : A room-temperature solid state laser for producing an output laser emission at any wavelength within a preselected range of wavelengths is disclosed. In a preferred embodiment,the laser comprises; a pump laser for emitting a CW pump beam at a preselected wavelength; a laser cavity defined by a first reflective element, an output coupler reflective element and a folded mirror disposed between the first reflective element and the output coupler reflective element to form a reflective path there among in the laser cavity; a laser crystal disposed in the laser cavity, the laser crystal being responsive to the CW pump beam at the preselected wavelength for producing a CW laser emission within a preselected range of wavelengths when the laser crystal is pumped the the CW pump beam at the preselected wavelength, the folded mirror operating to collimate the CW laser emission in the optical path between the folded mirror and the output coupler reflective element; and a tuning element disposed in the laser cavity between the folded mirror and the output coupler reflective element for tuning the collimated CW laser emission to any wavelength within the preselected range of wavelengths. jg
