Abstract
Owing to the small differences between the cross-sections of the four emission peaks around 1.3 μm, an efficient four-wavelength synchronous launched laser is demonstrated using a Nd:GdLuAG crystal. The laser has no special resonator design. The maximum output power is 4.28 W, which corresponds to a conversion efficiency of 45.6%. For the Q -switching, the laser operated in dual-wavelength mode, and the single pulse energy is maintained at ~ 80 μJ . By calculating the population inversion density, multi-wavelength emission characteristics in both continuous wave and Q -switching lasers are discussed.
