Abstract

We report a single-longitudinal-mode CW diode-pumped Nd:YVO4 laser emitting at both 1064 and 1342 nm with 10% optical efficiency at 20-W pump power. The measured spectral widths at 1064 and 1342 nm were less than 450 MHz and 400 MHz, respectively. The two emission wavelengths can be independently tuned over the lasing bandwidths of the dual-wavelength laser.

Schematic of the single-longitudinal-mode tunable dual-wavelength CW Nd:YVO4 laser. Mirrors M1 and M2 form the 1342-nm laser resonator, and mirrors M1 and M3 form the 1064-nm laser resonator. Narrow-line optical feedback at 1064 and 1342 nm are provided by M4 and M5, respectively, through a grazing-incident grating G. Rotating the angles of M4 and M5 independently tunes the 1064 and 1342 nm wavelengths, respectively.

(a) 1064-nm and (b) 1342-nm emission spectra of the dual-wavelength laser. Dashed lines are the laser spectra without grating feedback. Open dots are the spectral power with grating feedback, tuned at four mirror angles at M4 (a) or M5 (b). The inset shows the actual laser linewidth scanned by a Fabry-Perot spectrometer. The measured FWHM linewidths of the 1064-nm and 1342-nm lasers are 400 and 450 MHz, respectively.

The triangles are the total output power summed from the two curves. Ten-percent optical efficiency is achieved at 20-W pump power.
