Tunable Laser

The US Army is seeking a tunable laser with a wavelength range of 1480 to 1640 nanometers. The laser should have continuous-wave, mode-hop-free operation, a linewidth of less than 200 kHz, and a wavelength setting resolution of 0.1 picometers or better. The minimum output power should be 7 dBm across the tuning range, and the laser should have a fast wavelength sweep capability and fine tuning capability. The output should be compatible with standard single-mode fiber systems, and the laser should have remote control via USB, GPIB, and Ethernet interfaces. Some key features of the required laser include: • Tunable wavelength range from 1480 to 1640 nanometers • Continuous-wave, mode-hop-free operation • Linewidth less than 200 kHz • Wavelength setting resolution of 0.1 picometers or better • Minimum output power of 7 dBm across the tuning range • Fast wavelength sweep capability from 1 to 200 nm/s • Fine tuning capability over at least 10 GHz • Fiber-coupled output compatible with standard single-mode fiber systems
