How important is laser power
The size of the laser power is an important indicator of the laser process parameters. Only the appropriate green laser pointer power can ensure the long-term stable operation of the laser and the optical system, and it is also the decisive factor for achieving the best processing quality. As shown in Fig. 1, the conventional laser power monitoring device includes a thermal sensor and a control unit (not shown in the figure). The laser's resonant cavity emits laser light, and a 0.5% or lower power laser beam is transmitted through the tail mirror, which is irradiated on the thermal sensor, causing the temperature of the thermal sensor to change, and converting it into an electrical signal; the control unit receives the electrical signal, and Perform calibration; finally, externally display the actual output power of the monitored laser.

Do not exceed 50 modules in contact with the power port. Otherwise, the tail module will become dark due to the weakening of the voltage. Of course, when it comes to circuits, you can avoid weak situations, but don't overdo it. When the LED module that has not been waterproofed is installed in the LED luminous characters or box, measures must be taken to prevent rainwater from entering. The module spacing can be adjusted according to the brightness requirements. It is best to distribute 50 to 100 modules per square meter. When the light of the laser pointer is coming here and there, when you play with your cat, please shine it in a place that is safe for the cat as much as possible. Cats have strong arms, but they will slip and fall accidentally, so they are easily injured. Breaking valuable things is a loss. Therefore, I think it is best to set it as a safe route. Compared with the prior art, the high power laser pointer is equipped with a measuring device. The size of the beam spot is controlled by the measuring device. The laser beam can irradiate the product inconvenient to measure and the stains and scratches that are not obvious enough to be seen. It is easy to use for measurement and comparison of the product to be tested.
