ABSTRACT:
A linear cavity laser system having a yttrium-aluminum-garnet laser rod for producing a fundamental wavelength of radiation having a front face and a longitudinal axis, a first mirror reflective of the fundamental wavelength but transmissive of a desired harmonic wavelength located in front of the laser rod along the longitudinal axis, a second mirror reflective of both the fundamental wavelength and the desired harmonic wavelength located to a rear of the lasing rod along the longitudinal axis, a phase matched crystal harmonic wavelength generator responsive to the fundamental wavelength for generating the desired harmonic wavelength of radiation arranged between the front mirror and the lasing rod along the longitudinal axis and a dichroic member transmissive of the fundamental wavelength but reflective of the harmonic wavelength arranged between the laser rod and the harmonic wavelength generator along the longitudinal axis.
