Mode locking of travelling wave ring laser by amplitude modulation
Patent
·
OSTI ID:5963415
An amplitude modulator for a tunable ring cavity dye laser is disclosed. The modulator is operated in time synchronization with the laser pump and is located assymmetrically within the ring to attenuate dye laser pulses in one direction while passing pulses in the opposite direction, thereby producing a mode locked unidirectional travelling wave. The use of a low dispersion electro-optical modulator in a dye laser yields subpicosecond optical pulses with wide tunability.
