Sources Sought DEPT OF DEFENSE - DEPT OF THE ARMY is seeking one (1) Tunable Single Frequency Laser with specific wavelength and output power requirements. The laser should have a target wavelength of 479.9 nm, tuning range of ±0.4 nm, coarse tuning of 1 THz, and mode-hop free tuning range of > 2 GHz. It should also have an output optical power greater than 1 W at the target wavelength. The laser's maximum linewidths at 100 µs and 10 ms should be 10 kHz and 100 kHz respectively. Additionally, the laser should have a linearly polarized continuous wave TEM00 single mode profile with M2 < 1.2. Interested parties are requested to submit a capabilities statement addressing their past experience in manufacturing similar lasers, company information, and SBA Certified Socioeconomic status. All communication should be submitted electronically to Jimmy W. Creech at jimmy.w.creech.civ@army.mil.
