V. Kubecek et al., 4-W and 23-ps pulses from a lamp-pumped Nd : YAG laser passively mode-locked by polarization switching in a KTP crystal, APP PHYS B, 69(2), 1999, pp. 99-102
Passive mode-locking of a cw lamp-pumped Nd:YAG laser using nonlinear polar
ization switching in a type-II SHG crystal is reported. Light pulses with m
ore than 5 W of average power and pulse duration shorter than 25 ps have be
en obtained at 1064 nm.
