Is the handheld laser light a laser pointer?

The official name of the Laser pointer is "Laser pointer", which is different from ordinary laser pointers and stylus pens in that its shell is similar to ordinary flashlights, with larger volume and usually higher power. It is a pen-shaped transmitter that is designed to be portable, easy to hold, and processed into laser modules (diodes) with visible lasers. Common laser pointers include red light (650-660nm), green light (532nm), blue light (445-450nm) and blue-violet light (405nm).The laser flashlight is a semiconductor laser. The reason why it is different from the laser pointer is that its volume is easier to dissipate heat. The laser module is directly in contact with the aluminum flashlight housing. Generally, the flashlight module is relatively thicker and has better heat dissipation, so it is more stable than laser The pen is more superior (the laser pointer is a copper casing)! The power of laser flashlights generally ranges from more than 5mw to several hundred milliwatts. Some laser flashlights (such as blue laser flashlights) have power up to 1w. At the same time, some laser flashlights also have adjustable focus function, the laser beam is strong and clear, and the range is long. Most of them use rechargeable lithium batteries (such as 18650 rechargeable batteries).
