Abstract
We have developed green, blue, and red solid state lasers by diode laser pumping. A green laseroutputs up to 22 mW at 531 nm with an NYAB crystal, and a blue one up to 7 mW at 473 nmwith Nd: YAG/KNbO3 crystals. These visible lasers are efficient, compact, and reliable comparedwith flashlamp-pumped lasers or gas lasers. Many applications with these lasers arepresented.
