E. Sorokin et al., FEMTOSECOND SOLID-STATE LASERS USING ND3-DOPED MIXED SCANDIUM GARNETS(), Journal of the Optical Society of America. B, Optical physics, 10(8), 1993, pp. 1436-1442
The mode-locking features of a series of Nd3+-doped solid solutions of
aluminum and gallium garnets are investigated, and the influence of m
ultiline gain spectra on mode-locking performance is discussed. With a
n additive-pulse nonlinear Michelson interferometer used to mode lock
the laser passively, pulses as short as 260 fs are obtained. The effec
t of interferometer detuning on the pulse characteristics is studied.
