研究目的
Investigating the continuous-wave dual-wavelength laser operation of a Nd:GdVO4 laser using a single birefringent filter (BRF) plate.
研究成果
A continuous-wave dual-wavelength Nd:GdVO4 laser operating at 1063 & 1071 nm was developed using an intracavity birefringent filter. This approach allows for the adjustment of the power ratio between the two wavelengths or achieving single wavelength operation, which could be beneficial for applications in pulsed operation or nonlinear frequency conversion systems.
研究不足
The proximity of the 1071 nm emission line to the much stronger emission line at 1063 nm may limit the effectiveness of the BRF in achieving dual-wavelength operation at these wavelengths.
1：Experimental Design and Method Selection:
A three mirror cavity was used with a Nd:GdVO4 crystal as the gain medium. A single birefringent filter (BRF) plate was inserted at the Brewster’s angle near the output coupler to manage gain competition between different emission lines.
2：Sample Selection and Data Sources:
An a-cut
3：5 at.% doped Nd:
GdVO4 crystal with dimensions of 3×3×20 mm3 was used.
4：List of Experimental Equipment and Materials:
Fiber coupled laser diode operated around 912 nm, concave folding mirror (500 mm radius of curvature), flat output coupler (OC) with
5：4% transmission, and a 2-mm thick quartz birefringent plate filter. Experimental Procedures and Operational Workflow:
The pump beam was focused into the center of the gain medium. Rotation of the BRF plate around its surface normal resulted in dual-wavelength operation at 1063 & 1071 nm with different power ratios.
6：Data Analysis Methods:
Spectra were analyzed to determine the power ratio between the output wavelengths.
