Abstract

A frequency-stability and intracavity frequency-doubled ring Nd∶YVO

/KTP laser end-pumped by a laser diode was designed and experimentally demonstrated. The laser was single-frequency operated by using a TGG

a Brewster polarizer

and a half-wave plate acted as optical diode in the cavity. Under the incident power of 9 W

the maximum green laser output is 1.1W

and conversion efficiency from light to light is 12.2%. Also

a passively

-switched single-frequency laser in laser pulse duration of 100 ns and repetition rate of 21 kHz was achieved in a ring cavity by inserting a piece of Cr

∶YAG as an intracavity laser pulse saturable absorber.
