ABSTRACT:
A solid-state laser for generating harmonic laser light substantially at a desired wavelength has a pump diode body made of a first material, which is preferably aluminum, having a first coefficient of expansion and a laser diode mounted in the pump diode body for generating pump energy. A laser body assembly, which is positioned on the pump diode body, is made of a second material, which is preferably steel, having a second coefficient of expansion. The first and second coefficients of expansion of the respective pump diode body and the laser body assembly have a known relationship such that the laser cavity expands and contracts at a particular rate as the temperature of the laser increases and decreases to provide a substantially constant generation of the harmonic laser light. A laser gain chip mounted on an entrance mirror, which forms the back end of a laser cavity, generates fundamental laser light in response to pump energy from the laser diode. The fundamental laser light passes through an active etalon output mirror into a frequency doubler chip which doubles the frequency thereof to produce harmonic laser light. A mirrored surface, which forms a front end of the laser cavity, permits a portion of the harmonic laser light to be emitted from the laser and reflects the remaining portion of the harmonic laser light back to the active etalon output mirror. A control etalon may be provided to suppress undesired light wavelengths in the laser cavity.
