摘要：

To develop the application of new two-dimensional materials in frequency-doubled mode-locked lasers, ReSe2, an emerging kind of two-dimensional materials, is used as the saturable absorber mode-locking element in this study to examine the diode end-pumped Nd: YVO4 intracavity frequency-doubled green laser, thus obtaining the ReSe2 mode-locking green pulse laser with megahertz-level high repetition frequency and nanosecond-level narrow pulse width. The design of the compact V-shaped cavity and the intracavity frequency-doubled scheme are incorporated. The passive mode-locked oscillation of the fundamental frequency operates at 1064 nm. By exploiting the nonlinear crystals of LiB3O5 and KTiOPO4 for the second harmonic frequency conversion, the 532 nm frequency-doubled laser pulse is generated. With the LiB3O5 crystal for frequency doubling, the output repetition frequency of the continuous-wave mode-locked green pulse output is 87.51 MHz, the pulse width is 3.5 ns, and the average power is 240 mW. Under the same experimental conditions and with the KTiOPO4 crystal for frequency doubling, the maximum output power can be improved over 470 mW. The research results provide an available green pulse laser source for the development of underwater laser detection technology at high sampling rates. © 2021, Editorial Department of Journal of HEU.
