G&H launches pump combiners for high-power diodes
By Tim Hayes, Industry Editor, Optics & Laser Europe Magazine and optics.org.
Gooch & Housego, a manufacturer of components for high-power lasers and fibre amplifiers, has launched a range of low-port-count, multimode pump combiners with a signal feedthrough fibre. This configuration 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 is available as standard at centre wavelengths of 1064 nm and 1550 nm with both polarization maintaining and singlemode feedthrough fibres. The signal performance is essentially wavelength independent over the C band for 1550 nm devices and over a 60 nm range for the 1064 nm devices. Other options are available upon request including combiners with large-mode-area signal fibre.
The combiners are also available from AMS Technologies, which sells and markets Gooch & Housego products in Germany, the Netherlands, Belgium, Luxembourg, Spain, Portugal and Switzerland.
The new product line will be exhibited at LASER World of PHOTONICS 2009 by AMS Technologies at booth B1.301, and also by Gooch & Housego at booth B1.310.
