The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Construction of a 1014.8nm fiber amplifier for quadrupling into the UVGiuoco, Frank Joseph 30 September 2004 (has links)
A fiber amplifier is constructed at 1014.8nm and then frequency doubled to produce 507.4nm. This could then be frequency doubled again to produce 253.7 radiation. The fiber amplifier consists of Ytterbium doped double-clad fiber cooled to low temperatures and incorperates a diode laser as the seed source. The amplifier is built in a two stage configuration with high power diode lasers at 980nm pumping each stage. The output of the fiber amplifer is then doubled in a PPLN crystal and redoubled in a BBO cavity. Measurements are taken throughout the system to determine ouput powers from the first stage and from the fiber amplifier as a whole.
