473nm Blue DPSS Laser

473nm Blue DPSS Laser

473nm laser is different from other blue lasers(445nm/450nm/455nm laser).

The 473nm laser beam is not from 473nm Laser diode, it is illuminated by laser crystal, it’s a DPSS laser.

The 473nm laser generation process is that the 808nm laser is converted into a 946nm laser by a laser crystal.   After the frequency doubling crystal is converted into 473nm. Its production difficulty is even much higher than 532nm.
