Method for pumping a Ti:sapphire laser with a stable resonator copper vapor laser

An average laser power of > 3W and a slope efficiency of 20% have been obtained with a Ti:sapphire laser oscillator pumped by a copper vapor laser (CVL). A center-hole reflector inside a near-concentric resonator, instead of a dichroic mirror, has made it possible to utilize the stable resonator CVL as a pump source.
