Stability enhancement of femtosecond optical parametric oscillator based on dispersion management
A dispersion-managed femtosecond optical parametric oscillator (OPO) with stable power is demonstrated in this article. The OPO, based on LiB3O5 (LBO) crystal, was synchronously pumped by a frequency-doubled, Kerr-lens mode-locked Yb: CGYA laser. The output signal had a wavelength tuning range of 680 ~ 740 nm, a maximum average power of 1.1 W, and a minimum pulse duration of 105 fs. By inserting ultraviolet fused silica (UVFS) windows into the cavity to introduce additional normal dispersion, the dual-signal-wavelength output was suppressed, and the power stability was significantly enhanced. The RMS of the one-hour power fluctuation decreased to one seventh of its original value, from 2.47% to 0.38%. This work is of particular significance for promoting the engineering application of femtosecond OPOs.
