Am. Malyarevich et al., V-YAG - A NEW PASSIVE Q-SWITCH FOR DIODE-PUMPED SOLID-STATE LASERS, Applied physics. B, Lasers and optics, 67(5), 1998, pp. 555-558
We present the first use of V:YAG as a passive Q-switch for diode-pump
ed solid-state lasers. The ground- and excited-state absorption cross
sections of V:YAG were measured to be sigma(gsa) = 3.0 x 10(-18) cm(2)
and sigma(esa) = 1.4 x 10(-19) cm(2) at 1064 nm, and sigma(gsa) = 7.2
x 10(-18) cm(2) and sigma(esa) =7.4 x 10(-19) cm(2) at 1342 nm. Q-swi
tched operation was demonstrated at 1064 nm and 1342 nm from a Nd:YVO4
microchip laser, producing pulses as short as 9.3 ns at 1342 nm with
peak powers of 350 W.
