The specific embodiment
As shown in Figure 1, the green laser sub-marker of a kind of bull, comprise the laser instrument and optical beam path 5, control device and the workbench that are provided with in rack 1, the rack, described control device is a Servocontrol device, form by servo control box 3 and servomotor 7,8, servomotor has 3, and 1 servomotor 7 is connected with the focus lamp 4 of laser instrument and optical beam path, controls its z to motion; Workbench is the work of ball-screw guide rail, and workbench 8 is contained on the workbench cabinet 9.Two servomotor 8 orthogonal being contained on the workbench 8 are controlled the motion of workbench XY direction in addition; Laser instrument and optical beam path 5 have 2 covers, and 2 supporting with it cover Laser Power Devices 2 are contained in the rack; Laser instrument is electric-optically Q-switched frequency doubling pulse laser.
As Fig. 2, Fig. 3, shown in Figure 4, optically focused cavity 14 constitutes resonator with total reflective mirror 11 and half anti-mirror 15 that two ends are provided with; Wherein in the optically focused cavity 14 laser medium Nd is arranged 3+: YAG laser bar 19 and xenon flash lamp 20, the total reflective mirror 11 plating 1064nm film that is all-trans, the 1064nm half anti-film of half anti-mirror 15 plating transmitances 70%; Semiconductor pilot light 10 is housed before total reflective mirror 11; Electro-optic crystal 12 and polariscope 13 insert between total reflective mirror 11 and the optically focused cavity 14 transfers Q, improves laser peak power; Frequency-doubling crystal 16 carries out frequency multiplication after being loaded on half anti-mirror 15, obtains the green laser of wavelength 532nm; The laser of 532nm wavelength expands bundle through beam expanding lens 17, to press small divergence angle; Laser acts on crystal or glass material inside processes behind beam splitter 18 and focus lamp 4 then.
