Claim Text:
1. A stereoscopic projection system comprising: a first infrared laser; a first gain module that amplifies a light beam from the first infrared laser; a first second-harmonic generator (SHG) that frequency doubles a light beam from the first gain module; a first optical parametric amplifier (OPO) that parametrically amplifies a light beam from the first SHG; a second SHG that frequency doubles a first light beam from the first OPO; a third SHG that frequency doubles a second light beam from the first OPO; a second infrared laser; a second gain module that amplifies a light beam from the second infrared laser; and a fourth SHG that frequency doubles a light beam from the second gain module; wherein part of the light beam from the first SHG passes through the first OPO to form a remaining light beam, the remaining light beam has a first wavelength of green light, a light beam from the second SHG has a first wavelength of red light, a light beam from the third SHG has a first wavelength of blue light; and a light beam from the fourth SHG has a second wavelength of green light.
