On the basis of embodiment 1；
It is additionally provided with water cooling plant along described laser beam analyzer circumference, controls the temperature of laser beam analyzer, improve analysis
The analysis precision of instrument, and enable device described in the utility model that high-power laser instrument to be measured.
Embodiment 3:
On the basis of embodiment 1；
The power source driving described mirror holder to move is motor or hydraulic cylinder, uses motor or hydraulic cylinder to drive mirror holder,
The movement that can make mirror holder is steady and smooth and easy, it is ensured that the precision of measurement.
Embodiment described above only have expressed detailed description of the invention of the present utility model, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, common for this area
For technical staff, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these all belong to
In protection domain of the present utility model.
