Description

Technical Field

[0001] The utility model relates to the technical field of optical instruments, in particular to a picosecond laser. Background Art

[0002] The laser used in the beauty industry to remove spots and tattoos is a flash-pumped solid-state laser. Due to the upper energy level lifetime of the laser crystal Nd:YAG, the pulse width of a solid-state laser without a Q-switching device is in the hundreds of microseconds. The laser with this pulse length has low peak power and large thermal effect, which can easily burn the skin. On this basis, the laser can be Q-switched using an electro-optical modulator to compress the pulse width to the order of 10ns. The peak power of such a laser is increased by more than 1,000 times, and the thermal effect is reduced. It was a commonly used laser in the beauty industry in previous years, and picosecond pulse beauty lasers are another type of laser that has been popular in the industry in recent years.

[0003] When using an existing picosecond laser, the entire device is moved mainly through the moving wheels at the bottom of the laser. When using the laser, it is necessary to lock the moving wheels to ensure the stability of the device and avoid displacement of the laser. Although the moving wheels can be easily locked, the overall stability of the laser is still difficult to ensure due to the small number of contact points between the moving wheels and the ground. In actual use, the laser may shift. Utility Model Content

[0021] like Figure 1-5 A picosecond laser comprises a picosecond laser body 1, a fixed block 3 is fixedly arranged on the lower side of the picosecond laser body 1, a driving motor 4 is arranged on the lower side of the fixed block 3, a threaded rod 5 is fixedly arranged on the power end of the driving motor 4, a movable disk 6 is threadedly sleeved on the outer side of the threaded rod 5, a plurality of groups of connecting blocks 8 are fixedly arranged on the outer side of the movable disk 6, and movable blocks 9 are fixedly arranged on the outer sides of the plurality of connecting blocks 8, a plurality of groups of mounting grooves 11 for docking the movable blocks 9 are provided on the lower side of the fixed block 3, the movable blocks 9 are movably inserted into the mounting grooves 11, and a supporting block 10 is fixedly arranged on the outer part of the mounting groove 11 on the lower side of the movable block 9. When the picosecond laser body 1 is used, it only needs to turn on the driving motor 4 to drive the plurality of groups of movable blocks 9 and the supporting blocks 10 to move downward at the same time, and the plurality of groups of supporting blocks 10 can form a better support for the picosecond laser body 1, thereby ensuring the stability of the use of the picosecond laser body 1.

[0022] Among them, a plurality of groups of moving wheels 2 are symmetrically arranged on the lower side of the picosecond laser body 1 . By arranging the plurality of groups of moving wheels 2 , the picosecond laser body 1 can be conveniently moved as a whole, thereby ensuring the flexibility of use of the picosecond laser body 1 .

[0023] Among them, a fixed plate 7 is fixedly provided at the outer end of the threaded rod 5. By providing the fixed plate 7, the movable plate 6 can be limited to prevent the movable plate 6 from detaching from the threaded rod 5, thereby ensuring the continuous normal use of the device.

[0024] Among them, an inner groove 13 for docking the drive motor 4 is opened on the lower side of the fixing block 3, and the drive motor 4 is fixedly installed on the inner side of the inner groove 13. By setting the inner groove 13, the drive motor 4 can be easily installed, and at the same time, the drive motor 4 can also be protected to a certain extent, thereby improving the service life of the drive motor 4.

[0025] Among them, an anti-skid pad 14 is fixedly arranged on the lower side of the support block 10. The anti-skid pad 14 is made of soft material.

[0027] Embodiment: During use of the utility model, the picosecond laser body 1 is first moved to a suitable position by the push rod 15 and the moving wheel 2, and then the drive motor 4 is turned on by an external power supply. The drive motor 4 drives the threaded rod 5 to rotate, and the movable disk 6 sleeved on the outside of the threaded rod 5 moves downward along the threaded rod 5. When the movable disk 6 moves downward, it drives the connecting block 8 and the movable block 9 to move downward, and the movable block 9 slides downward from the installation groove 11 and drives the support block 10 to move downward until the anti-slip pad 14 on the lower side of the support block 10 contacts the ground, thereby increasing the contact point between the picosecond laser body 1 and the ground, ensuring the stability of the use of the picosecond laser body 1, and subsequently adjusting the drive motor 4 power end to rotate in the opposite direction through the external power supply. The same principle can drive the movable block 9 and the support block 10 to move upward, thereby facilitating the movement of the picosecond laser body 1.
