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在大气中传输时光丝形成机理。

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在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，其平源本钱相差较矮。

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.

在实际应中激光束要通过光学系统后与物质相互为了满足参数要求需要通过光学系统加以变换。
