The government intends to negotiate a sole-source award with Toptica Photonics, Inc. for a Continuously Tunable Laser System, as no other vendor's products meet the essential technical requirements. The required system includes a tunable laser with specific wavelength, power, linewidth, and control electronics, plus fiber couplers, a tapered amplifier, and optical isolators. This is a notice for information only, not a request for quotations, but responsible sources may submit a capability statement or proposal for consideration. Any response must demonstrate clear and convincing evidence that competition would be advantageous to the government. The government anticipates an award date on or before 30 September 2026.
