It must be pointed out that space coherence of beam is highly important for light beam quality evaluation.
此外还指出光束的空间相干性在光束空间质量评价中也应重视。
Its advantage is that the light beam quality is good, the light beam emitting direction and position can be changed optionally.
其优点在于光束质量好、可以任意改变光束的出射方向和位置。
This structure can solve the problems of catastrophic optical damage of facet, thermal damage and poor light beam quality effectively.
该机理能有效地解决光功率密度过高引起的端面灾变性毁坏、热烧毁和光束质量差等大功率激光器存在的主要问题。
