Continuous-wave operation of saturable-gain degenerate four-wave mixing in a Nd:YVO(4) amplifier.
We experimentally demonstrate for the first time to our knowledge continuous-wave operation of saturablegain degenerate four-wave mixing by using a Nd:YVO(4) amplifier pumped by a cw Ti:sapphire laser. Such an amplifier exhibits continuous-wave two-pass gains as high as 200, and four-wave mixing reflectivities as high as 30% are obtained. A theoretical analysis is developed in the steady-state regime to explain the experimental results.
