The experimental result shows that the depth of hardened zone and smoothness of surface can be controlled conveniently by varying the poweroutputbeam diameter and scanning rate of laser light.
试验表明：通过调节激光器的输出功率、光斑直径和扫描速度可以方便地控制熔化层深度和表面平整度。

A solid state laser operated at lower-order mixed mode possesses both advantages of high outputpower and good beam quality.
当固体激光器运转在低阶混合模时，既可得到较高的功率输出，又可保证较好的光束质量。
