Abstract

We describe a high-power blue laser for use in laser video projectors. The laser is based on an intra-cavity, frequency-doubled, Ti:sapphire resonator, longitudinally- pumped by a repetitively Q-switched 532 nm source. With 48 W of pump, the laser produces more than 7 W of continuously tunable blue output (430 <EQ (lambda) equals 460 nm) with a pulse width of 80 ns and a beam quality factor M² equals 2.2. The applicability of this high-power laser as a source of monochromatic blue light for different large-screen laser displays is also discussed.
