Intense excitation source of blue-green laser

Under a grant an intense excitation of a blue-green laser useful for underwater communication and detection system is being developed. The source in use, hypocycloidal-pinch plasma, can produce near uv photons which match the absorption spectra of solid state blue-green lasers such as Tb:YLF and dye lasers. The optical pumping method is efficient and simple for exciting short pulse lasers repetitively without coupling capacitor energy directly the laser medium. This document reports on progress made.
