报道了一种基于K3B6O 10 Br（KBB）非线性光学晶体的倍频绿色皮秒激光器，切割角θ = 34.7°，φ = 30°。采用尺寸为4mm × 4mm × 13.2mm的KBB晶体进行腔内倍频，获得了重复频率为80MHz、脉宽为25.0ps、平均功率为185.00mW的绿色ps激光输出。此外，我们还介绍了利用KBB晶体实现外倍频的方法。在重复频率为10 kHz、脉冲宽度为38.1 ps的条件下，获得了平均功率为3.00 W的绿色ps激光输出，脉冲能量为0.30 mJ，峰值功率为7.89 MW。实验结果表明，KBB晶体是一种很有前途的非线性光学材料。
We report a frequency-doubled green picosecond (ps) laser based on K3B6O10Br (KBB) nonlinear optical crystal with cutting angle of θ = 34.7° and φ = 30°. Through intracavity frequency doubling using a type I phase-matched KBB crystal with dimensions of 4 mm × 4 mm × 13.2 mm, the average output power of 185.00 mW green ps laser was obtained with a repetition rate of 80 MHz and pulse width of 25.0 ps. In addition, we present external frequency doubling using KBB crystal. The average output power of 3.00 W green ps laser was generated with a repetition rate of 10 kHz and pulse width of 38.1 ps, which corresponds to a pulse energy of 0.30 mJ and a peak power 7.89 MW, respectively. The experimental results show that KBB crystal is a promising nonlinear optical material.
