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 together if there is no ir filter.
510-520nm laser can work stably in low temperature environment. It doesn’t need time to warm up. The output power is more stable.

Disavantage:
