| 摘 要： | 光束合成是高功率固体激光器进一步发展的必由途径.板条的激光介质产生的矩形光束通过阵列合成能实现较高的近场光斑填充因子,有利于提高远场光束的能量集中度,从而获得更好的光束质量.根据激光器远场光束的测量方式,利用光束传输变换规律,建立矩形光斑双束合成的理论模型.通过数值模拟,在相干、非相干条件等典型情况下得到的子束合成不同...

| Abstract: | Beams combination is the only way for development of high power solid state lasers.Since the beam combination of rectangle beamlets from slab lasing mediums have larger fill factor of near-field spot,it can improve central energy of far-field spot and has better beam quality.According to measurement method of far-field spot of laser and propagation equation of Gaussian beam,the mathematical model of array combination for two rectangle beams was established.Applying this model,the intensity distributions in ... |
