Paper Abstract

We present an air-cooled optically pumped semiconductor laser that provides a cw output power of 1W at 488 nm. This performance was achieved via intracavity frequency doubling at a laser diode pump power of 2.5 Watts. The increased efficiency was realized by optimizing the OPS chip design and improving the heat extraction from the OPS chip. Efficient cooling of the OPS chip and a compact and mechanically stable folded resonator provide maintenance-free long life laser operation with an M2 of less than 1.1 and a noise of less than 0.25% rms. The size of the laser head is the same as for the 20 mW commercially available version, namely 125 x 70 x 34 mm.
