Abstract:
1. A method for operating a laser system comprising: generating with a pump laser pump laser pulses at a pump pulse frequency; inputting the pump laser pulses into a resonant cavity positioning a non-linear, non-critical phase matching crystal within the resonant cavity; generating multiple cavity modes inside the resonant cavity, each cavity mode being a wavelength at which standing waves occur within the resonant cavity; emitting a seed signal from a seed laser into the resonant cavity, the seed signal having a seed wavelength; electrically coupling a control unit to the seed laser; switching, via the control unit, the seed wavelength between the first seed wavelength and a second seed wavelength, the first seed wavelength having a first center wavelength proximate a first cavity mode and the second seed wavelength having a second center wavelength proximate a second cavity mode, there being at least two cavity modes between the first cavity mode and the second cavity mode; and modulating the seed laser at a seed pulse frequency at least as great as the pump pulse frequency.
