510-520nm green laser is diode laser. The green light directly comes from the laser diode. Meanwhile 532nm laser module need a 808nm laser diode and a crystal to convert 808nm light to 532nm laser. Compasiron between 510-520nm grass green laser and 532nm deeper green laser. Advantages: 510-520nm green light is purer than 532nm. 532nm has 808nm invisible laser mixed [...]
