PhotonTec Berlin has introduced a wavelength-stabilized 976nm diode laser with 60W output power through an optical fibre with 105µm core and NA 0.22.
Utilising volume grating, the centre wavelength of 976nm is locked and restricted to +/-0.5nm tolerance, and is insensitive to operating temperature and current.
The diode laser is hermetically packaged and incorporates photodiode and thermistor. A series of wavelength-stabilized diode lasers at 976nm and 981nm with power of 9W, 35W and 60W are available. Costmized power and wavelength are also available upon request.
The main application is fibre laser pumping.
