Patent ID: 7586961

Claim:
A laser source system for providing a laser output beam for delivery to a target in an optical instrument, the system comprising: two or more diode lasers; a control system in communication with said two or more diode lasers, said control system controls one or more outputs of the two or more diode lasers; one or more optical fibres delivering one or more output beams of the two or more diode lasers to a desired target; and coupling optics connected to said one or more optical fibres, the coupling optics receive the one or more output beams of the two or more diode lasers and direct the one or more output beams into the one or more optical fibres; and wherein: one or more of the diode lasers is arranged to be selectively operable over a range of output intensity that includes the diode laser's lasing threshold point, the range extends above and below the diode laser's lasing threshold point.
