Q-Switched Mode-Locking by Cascaded Second-Order Nonlinearity in a Nd:YVO4 Laser

Year: 2025

Type: article

Abstract: A diode-pumped Q-switched mode-locked Nd:YVO4 laser via a positive cascaded second-order Kerr lens using periodically poled MgO:SLT at 1064 nm was reported. Q-switched mode-locking performances, including pulse duration, output power, and bandwidth, were studied under different pump conditions. Under 28 W quasi-CW (QCW) diode pump peak power, the measured mode-locked pulse train, Q-switched repetition rate, and Q-switched pulse duration were 18 ps, 300 kHz, and 50 ns, respectively. The highest peak power of a single pulse near the maximum of the Q-switched envelope was greater than 150 kW.
