***The sole source determination is based on the National Institute of Standards and Technology's (NIST) requirement for DBR laser diodes: wavelength 780 and 850nm, >80mW output power, <1MHz linewidth, >30,000 hour lifetime. Photodigm is the only vendor that makes DBR laser diodes that meet the specifications at the wavelengths that NIST requires. NIST requires these specifications in order to be compatible with the existing system.
