“…To address mode competition from 1112 nm and 1116 nm, the implementation of Fabry-Perot (F-P) etalons or birefringent crystal (BC) placed according to Brewster angle proves effective in suppression. [13][14][15] However, the higher losses associated with the use of F-P etalons often result in lower output power and optical-to-optical conversion efficiency of the 1123 nm laser. When using BC, it becomes critical to accurately adjust the Brewster angle and the angle between the BC surface and the optical axis of the 1123 nm spectral light.…”

We report a high repetition frequency, high power stability and low laser noise laser-diode (LD) end-pumped Nd: YAG ceramic passively Q-switched laser at 1123 nm based on a Ti3C2T x -polyvinyl alcohol (PVA) film as a saturable absorber (SA). A Brewster polarizer (BP) and a birefringent crystal (BC) are incorporated to enable frequency selection and filtering for the passively Q-switched 1123 nm pulsed laser to improve the power stability and reduce the noise. When the pump power is 5.1 W, an average output power of 457.9 mW is obtained, corresponding to a repetition frequency of 1.09 MHz, a pulse width of 56 ns, a spectral line width of 0.65 nm, a power instability of ±0.92%, and a laser noise of 0.89%. The successful implementation of the “Ti3C2T x -PVA film passively Q-switching” combined with “frequency selection and filtering of BP + BC” technology path provides a valuable reference for developing pulsed laser with high repetition frequency, high stability and low noise.

Based totally on the intrinsic difference of polarizing emission spectra and birefringence of the a-cut Nd:YAP gain crystal, an orthogonally polarized 1079.5 and 1099 nm dual-wavelength laser is demonstrated. A specially designed dielectric Fabry-Perot filter is exploited as output coupler and gain balancer of the laser cavity. The maximum output power and slope conversion efficiency of the dual-wavelength laser is 976 mW and 7%, respectively. The experimental results show that the intrinsic birefringence of the laser gain material is the principle source for the generation of the orthogonal polarized laser. The competition between the two lasing wavelengths is analyzed and attributed to the stark energy levels involved. The method presented can be used to other biaxial laser gain crystals for the generation of orthogonal polarized dual-wavelength lasers.
