Abstract

A compact efficient continuous wave (CW) laser with selectable two wavelengths at 671 and 714nm is developed. The laser cavity comprises an Nd-doped and an undoped YVO4 crystal to generate the fundamental wave at 1342nm and the first-Stokes Raman wave at 1525 nm, respectively. A single LBO crystal with the cut angle in the XZ plane is designed to achieve the selectable phase-matching via the thermal tuning for the second harmonic generation (SHG) of 1342nm and the sum frequency generation (SFG) of 1342 and 1525 nm. At a pump power of 40 W, the optimal output powers at 671 and 714nm can reach 4.5 and 1.8 W, respectively. The present compact CW laser source at 671 and 714nm has practical usefulness for laser spectroscopy and numerous applications.
