RESUMEN
A flashlamp-pumped nanoparticle dispersion laser was demonstrated for the first time. The nanoparticles were Nd(2)O(3) modified with dimethyldichlorosilane (DMDCS) and dispersed in dimethyl sulfoxide-d(6) (DMSO-d(6)). The nanoparticle dispersion was pumped using four flashlamps to yield energy of 4.3 J in a 200 µs pulse, at a wavelength of 1057 nm.
RESUMEN
Lasing action from a dispersion of nanoparticles is reported for the first time to our knowledge. The nanoparticles are Nd(2)O(3) modified with dimethyldichlorosilane (DMDCS) in dimethylsulfoxide. The laser was pumped with a pulsed laser at 802 nm and yielded 2.7 mJ with a slope efficiency of 50%. This was compared to a standard Nd-doped phosphate glass that yielded very similar results in the same setup.
RESUMEN
A novel scheme for a flashlamp-pumped ultrahigh-gain laser amplifier is presented. It is based on a monolithic slab design achieving a gain of 10(5). The measured ratio between pulse and prepulse output power was 5x10(7).
