In this paper, uncooled 980 nm pump laser packaging technology was studied. The entire packaging technology involves optical, electrical, thermal, mechanical, etc., the accuracy of the order of microns. A miniaturized all-metal package with direct optical fiber coupling and a dual Bragg fiber-optic wavelength-locked technology eventually package a compact 980 nm pump laser with a fiber output of 120 mW over the operating temperature range of 0 to 70 ° C , And has better side mode rejection ratio and wavelength stability. To meet the optical fiber amplifier pump laser power, long life, high reliability, small size, low power consumption, low cost requirements laid the foundation.
