Paper Abstract

Developing a new UV cured organic polymer (called TEMA) with dopant of Rhodamine B, its gain characteristics have been investigated for various pumping schemes such as forward and backward edge-pumpings, and side-pumping, together with fundamental optical properties, i.e., absorption spectrum, absorption coefficient and fluorescence under pumping. Using a frequency-doubled Nd:YAG (532 nm) laser beam as a pumping source, a Nd:YAG (532 nm) laser-pumped dye 580 nm laser beam as a signal wave is amplified through the organic polymer gain medium, obtaining, thus far, the maximum gain of approximately 10 dB with the dopant concentration of 20 ppm for the path length 7 cm of bulk gain medium.
