Based on the latest RGB lasers, a Laser Digital Cinema Projector (LDCP) with 30,000 lm light output is manufactured. The reason why LDCP has the property of low power consumption is explained.
A highly efficient and compact continuous-wave (CW) 456 nm blue laser operation is demonstrated by using a diode end-pumped quasi-three-level Nd:GdVO4 emitting at 912 nm and using LBO as intra-cavity frequency doubling crystal. With the optimization of the operation conditions, the output power achieved 0.62 W at 456 nm and the optical-to-optical conversion efficiency (OCE) of 13.4 % at pump power...
The quasiphase matched PPMgLN crystal is used intracavity frequency doubled to obtain high power green laser, with a pump power of 20 W at 808 nm, 6.67 W output power at 532 nm is achieved.
