Device for simultaneous multiple-line mode locking of an argon-ion laser.
An acousto-optic device that can simultaneously mode lock multiple lines of a laser source has been designed and demonstrated. The device is an intracavity acousto-optic modulator with an end mirror. Multiple argon-ion laser lines at 476.5, 488.0, 496.5, and 514.5 nm were simultaneously modulated by using this device. Pulse trains with pulses having a width of approximately 100 psec FWHM at a repetition of 130 MHz were obtained for each line.
