All rights reserved. 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)B 2 O 3 -15Na 2 O-10PbO-5ZnO-5Li 2 O-xNd 2 O 3 (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 4 F 3/2 ® 4 I 9/2 , 4 F 3/2 ® 4 I 11/2 and 4 F 3/2 ® 4 I 13/2 respectively. The emission cross section relatively higher for the 4 F 3/2 ® 4 I 11/2 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 Nd 3+ label was obtained the maximum optical gain with incident power 900 mW.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Emission cross section,Glasses,Optical gain[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1016/j.matpr.2018.04.045[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
