Tunable Low-noise Short Wavelength Visible Coherent Light Source System NIST-SS26-126

NIST-SS26-126 PLEASE NOTE THIS A SOURCES SOUGHT NOTICE ONLY Title:? Tunable Low-noise Short Wavelength Visible Coherent Light Source System BACKGROUND The Quantum Measurement Division (QMD) at the National Institute of Standards and Technology (NIST) provides the fundamental basis for the measurement of mass, force, and vibration in the United States by maintaining and modernizing primary standards linked to the International System of Units (SI). The Division performs leading-edge research to develop advanced measurement technologies and provides calibration services that support U.S. industrial productivity and ensure equity in trade. The QMD has a requirement for a frequency-doubled fiber amplifier to generate 100 s of mW of coherent 780 nm light from < 10 mW of coherent 1560 nm light. This apparatus will be integrated into primary acoustic measurement systems, in support of the Division s mission to deliver accuracy and traceability of acoustic measurements. In order to meet the mission indicated above, the Mass and Force Group requires an apparatus for generating 200 mW or more of coherent 780 nm light from 10 mW or less of 1550 nm light. The minimum requirements are as follows: Line Item 0001: Description: Frequency-Doubled 1560 nm Optical Amplifier Quantity: One (1) Technical Specifications: Laser waveform: Continuous-wave Input wavelength: 1560 nm (+/- 2 nm) Output wavelength: Half of input wavelength Output power: 200 mW or higher Input power: 10 mW or lower Output polarization: linear with PER 17 or higher Output linewidth: 10 MHz or lower Fundamental rejection from output: 40 dB or higher Output power stability: 1 % or lower rms variation over 1 hour Input coupling: PM fiber, FC/APC termination Output coupling: PM fiber, FC/APC termination Instrument control: Front panel control AC power supply: 60 Hz 115 VAC Form factor: A single unit, fitting in a standard 19 rack, or smaller.
