laser beam

The mechanism of filamentation formed by femtosecond pulse laser beam propagating in atmosphere is investigated.

分析了飞秒激光脉冲大气中传输时光成机理。

And traditional rotating mirror, bolographic refringence microscopic engage laser beam scanning in sencitivity on imamging.

和古板回旋扭转镜背不同，全息不直射镜也是让激平束扫描感平质料上成像机构。

In order to achieve optimum productivity, often polybromide laser beam parallel record technology, its light source cost relatively expensive.

为了到达不宜出产效果，不常拔取众激平束并行纪录技艺，其平源本钱相差较。

In the usual lives, laser beam need either propagation through optical system to interreact with other material or in order to satisfy the parameter require.

际应用中激光束要通过光学系统后与物质相互作用或为了满足参数要求需要通过光学系统加以变换。
