Patent ID: 8724671

Claim:
A system for generating multiple simultaneous laser wavelengths, said system comprising: a pulsed slave laser comprising a non-linear electro-optic crystal optically coupled to a lasing crystal in a ring cavity configuration, said non-linear electro-optic crystal configured to adjust an optical path length of said ring cavity in response to an applied voltage potential; an energy pump configured to initiate a pulse cycle in said pulsed slave laser in response to a flash trigger; a master seed laser configured to inject a first single frequency laser beam into said pulsed slave laser; a slave seed laser configured to inject a second single frequency laser beam into said pulsed slave laser; and a cavity control circuit configured to: apply said voltage potential to said non-linear electro-optic crystal; ramp said voltage potential from an initial voltage to a final voltage, said final voltage associated with detection of a cavity resonance condition associated with said adjusted optical path length, said cavity resonance condition matching a resonance condition of said master seed laser; maintain said voltage potential at said final voltage for a pre-determined hold-time period; de-tune said slave seed laser, during said hold-time period, such that said slave seed laser matches said cavity resonance condition; and provide a Q-switch trigger to said energy pump within 30 microseconds of the start of said hold-time period.
