Title:
MODULATION METHOD FOR DIODE-LASER PUMPED LASERS
Document Type and Number:
WIPO Patent Application WO/2012/010688
Kind Code:
A3
Abstract:
A method of operating a digitally modulated solid state laser is disclosed. The laser is optically pumped by a current - supply driven diode- laser (16) radiation and with output-power stabilized at a desired value by a light regulator (28A) cooperative with a power monitor (24) and the current source (32) is disclosed. When the laser is turned on, the current - source (32) is enabled and the light- regulator (28A) is disabled. A current regulator (60) allows current from the current - supply (32) to increase until the monitored power reaches the desired value. At this point, the light regulator (28A) is enabled and the light regulator assumes control of the current - supply for maintaining the output-power at the desired level.
