Title:
PULSE LASER
Document Type and Number:
WIPO Patent Application WO/1996/036857
Kind Code:
A1
Abstract:
A pulse laser which outputs a pulsed laser beam, comprises a delaying means which delays the timing of shift from off to on of a laser output timing signal which is turned on during the output period of the pulse laser for the time required to output one laser pulse and an average output measuring means which measures the average output of the pulse laser while the laser output timing signal is on. The average output of the pulse laser is accurately measured by eliminating the influence of giant pulses.
