How much is laser pointer speed?Ordinary light propagation speed in the air is 300,000 meters per second. Laser propagation velocity in air is 300,000,000 meters per second. Laser propagation velocity in the air is 3/4 of vacuum. Laser propagation velocity in the glass is 2/3 of vacuum.Safety measures of laser pointer operation:● Laser pointer at room temperature can up to the brightest begin using. The continuous lighting should not exceed 30 seconds.● Laser is harmful to eyes. Do not air at eyes illumination. Please wear appropriate laser safety goggles indoors or close to the blue laser pointer. Avoid direct pointing of laser pointer at eyes. Laser irradiation up 30mW cannot face the human body, in order to avoid accidental injury.● Keep laser pointer away from children, and prevent danger from the improper use of laser pointer. Remove the battery and saved when laser pointer is not in use.● Please pay attention to battery or replace battery if found severely reduce of brightness of laser beam.● Do not continuous light laser too long (especially green laser), in summer it is best no more than 30 seconds. Please immediately stop use until it is completely cool if you feel laser pointer is hot. The best time to use high powered laser pointers in controlled time of 1 minute, turn off 5 minutes for cooling and then open. It can prevent excessive aging of laser pointer, or laser diode damage caused by overheating. These indications can protect laser pointers a longer serving lifetime.

Laser Pointer FAQ(2)

Post on: April 23,2019
Why laser diode and crystal of laser pointer can be easily burnt out?Long working hours is a key point which can cause laser diode burnt out. Due to long working hours, laser temperature increases with the increase of working hours, resulting in damage to the laser diode and crystal.When laser pointers require preheating? Laser pointer crystal is composed of yttrium vanadate crystals (YVO4), of which yttrium vanadate crystals are very sensitive to temperature, stable operating temperature at 20 ° -30 °, yttrium vanadate crystals stimulate operating temperature 20 °. When the outside temperature is below 20 °, yttrium vanadate crystal would be difficult to start. The lower the ambient temperature, the longer startup time will be spent on laser pointers.Why green laser pointer power will decay at a high temperature?Green laser pointer consists of 808nm laser diode and crystal, operating temperature of 25°, laser diode wavelength 808nm±2nm. When operating temperature is up 25 °, laser diode wavelength will be shorter, thus laser power reduces along with wavelength change. The longer the operation time of laser pointer, the higher the temperature and the power will also decay.

Laser Pointer FAQ (1)

What is the difference between red and green laser pointer?Wavelength difference. Red laser wavelength is between 635nm to 780nm. Green laser wavelength is 515nm, 520nm and 532nm.Different light emitting mode. Red laser pointer emit light directly from laser diode, without extract devices. It emits bright light directly from red laser diode. 532nm green laser light is emitting from 808nm laser diode pump crystal.Why blue violet laser pointer light spot is very weak?According to the principle of lasers, in case of same power, the shorter wavelength laser pointer can emit brighter light than longer wavelength one. However, the perspective of 532nm wavelength light is more easily absorbed and more sensitive, light emitting from 405nm blue violet laser looks much weaker to human eyes.Why red laser beam is not as visible as green laser?Shorter wavelength laser has great loss in the atmosphere, thus green laser pointer is more easily visible than red laser beam. Green laser light is more easily absorbed by dust in the air, green laser pointer is more easily reflective, and thus beam of green laser pointer is much more visible than red laser pointer.How long can green laser pointer can be lighted?The continuous lighting time of green laser pointers will vary depending on output power. Portable green laser can be lighted within 10 seconds under formal working temperature of (25 °). If operating time is extended, the output power might be increased in attenuation, until not bright. Long operation time can destroy laser diode and crystal, or even burn out laser diode. Industrial alignment laser can be operated 24 hours continuously a day under room temperature and correct cooling system. The portion of alignment laser should be fixed in operation.
