25 April 2000 RGB optical parametric oscillator source for compact laser projection displays

A compact and efficient laser source is required as an enabling technology for laser projection displays. We discuss a scalable green-pumped, non-critically phase- matched LBO optical parametric oscillator (OPO) which simultaneously generates red and blue wavelengths that are ideal for display applications. Pumping the OPO with 9.7 W of 523 nm green light from a frequency-doubled, diode-pumped Nd:YLF oscillator/amplifier laser system has resulted in a measured 4.0 W of 896 nm signal power and an estimated idler power of 2.8 W. The signal was extra-cavity frequency doubled to produce 1.10 W of blue light at 448 nm. Intra- cavity frequency doubling of the idler produced 1.95 W of red light at 628 nm.
