Efficient high-energy SHG using a triaxial flashlamp-pumped dye laser.
A triaxial flashlamp-pumped dye laser is described. It has sufficiently good beam quality to allow efficient high-energy SHG. This laser consists of a tunable oscillator and a single amplifier that operate in the vicinity of 610 nm. The harmonic generator is an angle-tuned KDP crystal that utilizes cylindrical focusing optics. Typical energy output at 305 nm is 100 mJ at a doubling efficiency of 12%.
