Electro-optic harmonic conversion to switch a laser beam out of a cavity
A method is described for using electro-optic harmonic frequency conversion to switch a laser beam out of a laser cavity, comprising: providing a laser cavity defining a closed optical path centered about an optical axis running in the closed optical path comprising two end mirrors, at least one amplifier medium, and at least one electro-optic harmonic conversion crystal; pumping the at least one amplifier medium; injecting a laser pulse into the laser cavity to travel in the closed optical path; amplifying the laser pulse until a desired laser light energy is reached; applying an electric field across the electro-optic harmonic conversion crystal in an effective amount for substantially converting the desired laser light energy to a harmonic frequency; and permitting the desired laser light energy, and after being harmonically converted, to be substantially transmitted as a laser beam outside of the laser cavity.
