Compact and high repetition rate Kerr-lens mode-locked 532 nm Nd:YVO₄laser

Abstract

A compact and feasible CW Kerr-lens-induced mode-locked 532 nm Nd:YVO 4 laser system was experimentally demonstrated for the first time with theoretical analysis. Kerr-lens mode locking with intracavity second harmonic generation provides a promising method to generate a high-repetition-rate picosecond green laser. With an incident pump power of 6 W, the average output power of mode locking was 258 mW at a high repetition rate of 1.1 GHz.

“…The advantages of high peak power, high beam quality and short pulse duration of ultrashort lasers make them suitable for a wide range of applications. Their typical applications can be named as high-precision machining [1,2], high-precision ranging using time of flight techniques [3,4], nonlinear frequency generation [5][6][7][8] and advanced laser spectroscopy [9,10]. Similar to other types of lasers, the development tendency of picosecond laser includes high average power, high energy, high beam quality, and high stability.…”
