The use of wireless laser pointers has gradually developed
The continuous lighting time of the green laser pointer will vary depending on the output power. The portable green laser will light up within 10 seconds at normal operating temperature (25°). If the working time is prolonged, the output power may increase and attenuate until it does not light up. Long-term operation will damage the laser diode and crystal, or even burn the laser diode. The industrial calibration laser can run continuously for 24 hours at room temperature and cool the system appropriately. The part aimed at the laser should be fixed during operation. Ordinary light travels through the air at a speed of 300,000 meters per second. The laser travels through the air at a speed of 300 million meters per second. The laser propagates in the air at 3/4 the speed of the vacuum. The laser propagation speed of glass is 2/3 of that of vacuum.
