532nm 10W DPSS Laser with Green color beam is mainly used in Labs. The 532 nm diode lasers have a output power range from 1mW to 30,000mW ( 30W ) .

There is no 10 watt handheld green laser, many handheld green lasers labelled 10 watt are not real output power.

Here are some manufacturers for 10w DPSS laser:
