Have you seen the 50mw green laser diode?

Before the green laser diode, we must first understand what a green laser is. Green laser refers to the light amplification generated by stimulated radiation and is a high-quality light source. Usually the Laser pointer with a laser wavelength of 492nm to 577nm is called a green laser. Laser diodes with laser wavelengths within this range are collectively referred to as green laser diodes. At present, the common Green laser pointer diodes on the market are 520nm and 532nm. Since the human eye is most sensitive to the 532nm wavelength, the color of the 532nm laser wavelength is the easiest to recognize, with higher color purity and brighter beams. The laser diode is a light source semiconductor laser invented in the 1960s, also known as the laser tube (Laser Diode). LASER is an abbreviation of "Light Amplification by Stimulated Emission of Radiation", usually abbreviated as LD. Since it can produce light with exactly the same properties such as wavelength and phase, high coherence is its biggest feature.
