Antiresonant nonlinear mirror for passive laser mode locking
Patent
·
OSTI ID:5047585
The present invention relates in general to nonlinear mirrors, and in particular to antiresonant nonlinear mirrors for passive mode locking of lasers which do not require active length stabilization. Various techniques of passively mode locking lasers have been developed which use two coupled cavities, one with gain and one with a nonlinear optical element or mirror which returns to the laser cavity an optical pulse shorter in duration than that which was incident on it. Stankov, A Mirror with an Intensity-Dependent Reflection Coefficient, Applied Physics B, Vol. 45, pp. 191-195 (1988), describes the use of one type of nonlinear mirror with power (intensity) dependent reflection to mode-lock a Nd:YAG laser and thereby obtain short light pulses.
