Tunable Cateye SAF Lasers (CES)
The MOGLabs CES cateye laser combines the advantages of cateye filter technology with unique butterfly-packaged single angled facet laser diodes. The CES achieves extremely low linewidth (5 kHz) and very broad tuning range, with integral Faraday isolator and fibre-coupled output.
Currently available wavelengths and peak power: 960 – 1080nm, 200mW* 1080 – 1200nm, 100mW* 1170 – 1270nm, 40mW 1250 – 1390nm, 70mW 1420 – 1520nm, 40mW 1510 – 1610nm, 40mW 1860 – 1970nm, 7mW*
Notes: 1. Full wavelength range requires swapping filters. 2. Devices marked with * do not include internal Faraday isolator.
