Abstract

As 808 nm single emitter diode lasers have low output powers

they are limited to pump neodymium-doped double-cladding fiber lasers in end pumping. In order to enhance the pumping efficiency of the fiber laser by using single emitters

a fiber coupled module with several single emitter diode lasers was developed. First

the fast axis and slow axis of each diode laser were collimated by a micro-lens. Then

the output beams of diode lasers were combined with reflecting prisms. Finally

a suit of optical system designed by ourselves was utilized to expand and focus the beam into a optical fiber. Experiments show that this approach can greatly increase the brightness of the module with fiber coupled LDs. Four LDs with continuou output power of 5 W are coupled in a 105 m multimode optical fiber with a core diameter of 105 m and a numerical aperture of 0.2 when the working current is 5.8 A

it can offer the fiber output power of 15.22 W

coupling efficiency of 74% and the brightness over 1.4 MW/cm

sr.
