abstract = "We demonstrate a compact high-power green (532nm) laser module based on single-pass second harmonic generation. The pump source is a distributed Bragg reflector tapered diode laser. The frequency conversion is achieved with a 2.5 cm long periodically poled MgO:LiNbO3 bulk crystal. The entire module is integrated on a compact micro-optical bench with a footprint of 2.5 cm 3. Up to 1.1 W output green light power is achieved at a pump power of 7.6 W with an optical conversion efficiency of about 15\% and a corresponding module wall-plug efficiency of more than 4\%. The green laser beam has a relatively good beam quality (measured at output power level of ∼0.9 W) with M2σ=1.8 in the vertical direction and M 2σ=4.9 in the lateral direction, respectively. The long-term output power stability is ±10\% (tested at output power level of ∼0.6 W).",
