Tunable diode laser at 852 nanometers and tunable between 830 and 870 nanometers, with a minimum power output of 85 milliwatts at 852 nanometers, and anti-reflective coating. The laser chassis includes both the diode laser and a Faraday optical isolator capable of 60 dB of attenuation. The diode laser controller must be digital.
