Multi-Channel Laser Interferometer for UHV Optomechanical Sensing

The National Institute of Standards and Technology (NIST) is conducting market research to identify alternative sources for a multi-channel laser interferometer for UHV optomechanical sensing. The required system must provide picometer-class displacement resolution with a measurement bandwidth of at least 2.5 MHz across all three channels simultaneously. The system should consist of a three-channel Michelson interferometer controller, a breakout box for analog and digital signal access, and three ultra-high-vacuum-compatible focusing sensor heads. • The system must be compact and ultra-high-vacuum-compatible. • The system must provide picometer-class displacement resolution. • The system must have a measurement bandwidth of at least 2.5 MHz across all three channels simultaneously. • The system must have miniature all-optical (electronics-free) sensor heads rated to a base pressure of 1×10–11 mbar. • The system must have a stabilized, NIST-traceable laser source operating in the 1510–1560 nm range.
