Abstract

In this paper we develop the optical pumping system based on 805 nm laser diode as photo-pumped source. Laser with a wavelength of 1064 nm is used as reference source and passed in a laser glass medium. Laser glass medium was synthesized from chemical compositions of (65-x)B2O3-15Na2O-10PbO-5ZnO-5Li2O-xNd2O3 (with x = 0.05, 0.1, 0.5, 1.0, 2.0 and 4.0). The emission spectra confirms that there are three emission peaks located at 946 nm, 1064 nm and 1350 nm corresponding to 4F3/2®4I9/2, 4F3/2®4I11/2 and 4F3/2®4I13/2 respectively. The emission cross section relatively higher for the 4F3/2®4I11/2 transition shows the compatibility of these glasses for near infra-red laser application. The measurements of optical gain had been carried out by using lock-in amplifier with voltage as output signal. From output voltage converted to optical gain in dB. The glass medium with 1.0 Nd3+ label was obtained the maximum optical gain with incident power 900 mW.
