Laser-diode end-pumped intracavity frequency doubling semiconductor saturable absorber mirror passively mode-locked picosecond lasers

A diode pumped Nd:YVO 4 semiconductor saturable absorber mirror (SESAM) passive mode-locked intracavity frequency doubled laser was studied. A type II phase matching KTiOPO 4(KTP) crystal and a type I phase matching LiB 3O 5 (LBO) frequency doubling crystal were respectively inserted in the cavity....

Zusammenfassung:A diode pumped Nd:YVO 4 semiconductor saturable absorber mirror (SESAM) passive mode-locked intracavity frequency doubled laser was studied. A type II phase matching KTiOPO 4(KTP) crystal and a type I phase matching LiB 3O 5 (LBO) frequency doubling crystal were respectively inserted in the cavity. With a pump power of 4.5 W, a 90 mW output of frequency doubled beam and 29.7 ps pulse duration were achieved with frequency doubled by KTP. With the same pump power a 140 mW output of frequency doubled beam and 3.67 ps pulse duration were achieved with LBO.
