This patent describes a method for harmonically generating coherent, optical radiation from a non-linear optical material, comprising the steps of: generating a beam of coherent, optical pumping radiation of a first optical wavelength from a diode laser; directing the beam of optical pumping radiation derived from the laser diode into a member of lasant material for efficient, optical pumping of the lasant material and to excite coherent, optical lasant radiation at a second wavelength; interacting the coherent, optical lasant radiation at the second wavelength with a member of non-linear, optical material to harmonically generate coherent, optical radiation at a third wavelength harmonically related to the lasant radiation at the second wavelength; resonating the coherent, lasant radiation at the second wavelength by reflecting the lasant radiation between optical reflectors for the second wavelength with the resonated, lasant radiation as reflected between the reflectors also passing through the lasant material and through the non-linear, optical material, and forming at least one of the optical reflectors on a face of the lasant material and forming a second one of the optical reflectors on a face of the non-linear, optical material.
