ABSTRACT:
This invention relates to a method and apparatus for tuning a laser amplifier, which amplifier utilizes a laser medium capable of lasing over a selected broad wavelength band. The lasing medium is pumped and a selectively tunable optical parametric generator (OPG), such as an optical parametric amplifier or an optical parametric oscillator, is driven with an optical signal at a wavelength such that the OPG, as tuned, generates an output at a selected wavelength within the broad wavelength band of the lasing medium. The output from the OPG is injected as a seeding input to the lasing medium to adjust the lasing wavelength thereof. All components of the system are preferably solid state components and the OPG is preferably driven from the pumping source so as to assure proper synchronization.
