Application Notes

AC designs and manufactures a lasre to fiber coupler which coupler light from a collimated source into a singlemode fiber, a polarization maintaining fiber, or a mulitimode fiber. It can handle wavelength from 400nm to 1700nm and inputpower up to CW 10W. The coupler is ideal for He-Ne lasers, Argon lron lasers, and Nd: YAG lasers etc. The coupling efficiency is typically large than 55% for singlemode and large than 80% than multimode.
