Title: Automatically tunable UV to IR laser system 

BACKGROUND

The National Institute of Standards and Technology (NIST), Sensor Science Division (SSD), Remote Sensing Group (RSG), Primary Optical Watt Radiometer (POWR) lab requires an automatically tunable ultraviolet (UV) to infrared (IR) laser system to be used in conjunction with the Primary Optical Watt Radiometer (POWR), which serves as the Nation’s optical power reference. POWR, an absolute cryogenic radiometer, measures the optical power from a minimally diverging light source and uses that same light source to then calibrate the responsivity of different types of detectors, which are then used as optical power standards. The detectors used are primarily Si photodiodes/traps (for the UV to near-IR) or InGaAs photodiodes (for the IR). The laser system shall be used for setting the UV to IR optical power scale/standards and must be capable of providing light that can be tuned, at least, between 190 nm to 2300 nm with continuous wavelength tuning. Additionally, a narrow spectral bandwidth (≈10 cm−1) at each chosen wavelength is required. Automatic (i.e. computer controlled/programmable) tuning of the system is essential so that time-efficient calibrations of detectors can be performed in the specified wavelength range.

Contract Line-Item Number (CLIN) 0001: The Contractor shall provide one (1) automatically tunable UV to IR laser system to carry out measurements which set the Nation’s reference scale for optical power.  

The system shall meet or exceed the technical specifications identified below. All items must be new.  Used or remanufactured equipment will not be considered for award. Experimental, prototype, or custom items will not be considered.  The use of “gray market” components not authorized for sale in the U.S. by the Contractor is not acceptable.  

1. The laser system output shall provide light with wavelengths between 190 nm and 2300 nm, where one wavelength at a time can be selected within the specifications of [3] and [4]. 

1. The laser system shall have continuous wavelength selection tunability throughout the entire wavelength range, 190 nm to 2300 nm. 

1. The spectral bandwidth full-width-at-half-maximum of the laser system output must be approximately 10 cm−1 or less for each selected wavelength throughout the entire wavelength range, 190 nm to 2300 nm. Spectral impurities outside of the selected wavelength should be well-characterized and filtered/filterable if present. 

1. The reproducibility of selecting a specific wavelength should be less than 0.5 nm across the entire wavelength range, 190 nm to 2300 nm.  

1. The average power of the laser system output must be greater than one milliwatt at each selected wavelength within the wavelength range 190 nm to 230 nm, and approximately greater than ten milliwatts across the rest of the wavelength range, 230 nm to 2300 nm. 

1. The laser system must be fully automated, meaning the entire wavelength range should be tunable via a provided control computer with the control software pre-loaded (a backup control computer with software is also required). The control software should include a standard interface (e.g. TCP/IP) that allows the user to remote control the software with a fixed set of provided commands.  

1. Wavelength changes should be able to be made without user intervention. However, manual intervention between the wavelengths of 190 nm and 230 nm is okay. 

1. The output beam profile should be Gaussian-like, with M2 < 1.3. ​ 

1. The pointing stability of the laser system output must be less than 500 microrad.  

1. The laser system must fit on an L-shaped optical table, where the surface dimension limitations for each side of the L are 2 m x 0.8 m.  

1. The power requirements for all components of the laser system must be compatible with 100 V to 240 V AC single phase electrical outlets.   

If the laser system output is created from a pulsed laser source, then the following minimum requirements must be met: 

1. The repetition rate of the pulsed laser shall be quasi-continuous, meaning the repetition rate should be greater than 1 MHz. 

1. The pulse duration of the pulsed laser should be in the picosecond range.  

1. The pulse energy stability of the pulsed laser should be less than 2% (rms). 

NIST conducted market research from June 2024 – August 2024 by, speaking with colleagues, performing internet searches, and speaking with vendors to determine what sources could meet NIST’s minimum requirements.  The results of that market research revealed that only APE APPLIED PHYSICS & ELECTRONICS, INC. (UEI: HGJ7PE8KFM14) can meet all the Governments minimum requirements. Particularly, the combination of fast pulse repetition rate (80 MHz) of the pump laser and narrow final spectral bandwidth (10 cm−1), combined with full computer automation tuning of the wavelength and average optical power (> 1 mW), is unmatched by other products.
