08 Jun 2009 Gooch & Housego, a leading manufacturer of high power laser and fibre amplifier components has launched a range of low port count, multimode pump combiners with a signal feed through fibre. This is commonly referred to as a 2+1x1. Fibre laser systems incorporating the 2+1x1 are becoming more common as diode pump powers increase. They are already established as the signal/pump combiner in high power fibre amplifiers for CATV distribution.
The 2+1x1 combiner is built with similar techniques and processes to those used in the manufacture of the high quality, high reliability fused couplers for which G&H is renowned. Again G&H have developed and now manufacture a best in class component with the highest signal and pump transmission efficiencies currently available on the market. |
