Abstract
We present a CW intracavity frequency-doubled laser oscillator pumped at , producing of green light at with and RMS noise of 0.05%, thanks to the simultaneous oscillation of a large number of longitudinal modes. A diode-to-green optical efficiency of 29% is achieved by the use of a noncritically phase-matched lithium triborate crystal inserted in a periodic resonator containing two crystals pumped with a total of at .
