A high-power low-noise continuous-wave green laser at 532 nm is developed by the single-pass frequency doubling of a single-frequency 1064 nm Yb-doped fiber amplifier in a MgO-doped periodically-poled stoichiometric lithium tantalate crystal. More than 10 W is obtained with a conversion efficiency of 38.3%. The linewidth of the green laser is estimated at about 3.4 kHz according to the linewidth of 1.7 kHz of the fundamental laser. The relative intensity noise integrated from 100 Hz to 10 MHz is less than 0.03%. The laser is a promising candidate for applications in quantum simulation with ultracold atoms and the pumping of Ti:sapphire lasers etc.

通过单频光纤放大器的单通倍频产生10 W低噪声绿色激光

通过在掺MgO的周期极化化学计量钽酸锂晶体中单频1064 nm掺Yb的光纤放大器的单通倍频，开发出了532 nm的高功率低噪声连续波绿色激光器。获得超过10 W的功率，转换效率为38.3％。根据基本激光器的1.7 kHz的线宽，估计绿色激光器的线宽约为3.4 kHz。从100 Hz到10 MHz积分的相对强度噪声小于0.03％。该激光器是超冷原子量子模拟和泵浦Ti：蓝宝石激光器等方面的有希望的候选者。
