Abstract
An efficient high-power dual-wavelength lime-green Nd:YVO4 self-Raman laser is inventively developed by using two different lithium triborate (LBO) crystals. The first and second LBO crystals are employed to generate the 559nm lime and 532nm green lasers, respectively. The temperature of the first LBO crystal is fixed at the optimal phase matching, whereas the temperature of the second LBO crystal is tuned to flexibly control the relative strengths between the 532 and 559nm waves. When the temperature of the second LBO crystal is set for the maximal total output power, the 532 and 559nm output powers, respectively, are 7.1 and 2.9W at a pump power of 31.6W, corresponding to a conversion efficiency of 31.6%. When the temperature is controlled for the balanced output, the 532 and 559nm powers, respectively, are 4.3 and 4.2W at a pump power of 31.6W, corresponding to a conversion efficiency of 26.9%.
