摘　　要：将激光器阵列的各个子激光光源进行相干合成,从而获得相干阵激光输出,这是得到高光束质量、高功率激光输出的一种有效方法。根据光束质量国际标准,采用桶中能量(功率)比计算相干阵激光远场的光束桶半径,通过拟合得到相干阵激光光束传输的双曲线方程,从而计算出相干阵激光器光束质量M^(2)因子。计算结果表明,相干阵激光器的光束质量接近基模高斯光束的光束质量。It is an effective method to obtain high beam quality and high power laser output by coherently combining each sub-laser source of the laser array.According to the international standard of beam quality,the bucket radius of coherent array laser is calculated by the energy or power ratio in the bucket.And the beam quality factor M^(2) of coherent array laser is calculated by fitting the hyperbolic equation of laser beam transmission.The results of calculation show that the beam quality of coherent array laser is close to that of fundamental mode Gaussian beam.
