Massachusetts Institute of Technology et al.; Notice of Decision 
on Application for Duty-Free Entry of Scientific Instruments

    This is a decision pursuant to section 6(c) of the Educational, 
Scientific, and Cultural Materials Importation Act of

[[Page 73633]]

1966 (Pub. L. 89-651, as amended by Pub. L. 106-36; 80 Stat. 897; 15 
CFR part 301). OnJuly 25, 2024, the Department of Commerce published a 
notice in the Federal Register requesting public comment on whether 
instruments of equivalent scientific value, for the purposes for which 
the instruments identified in the docket(s) below are intended to be 
used, are being manufactured in the United States. See Application(s) 
for Duty-Free Entry of Scientific Instruments, 89 FR60354-55, July 25, 
2024 (Notice). We received no public comments.
    Comments: None received. Decision: Approved. We know of no 
instruments of equivalent scientific value to the foreign instruments 
described below, for such purposes as this is intended to be used, that 
were being manufactured in the United States at the time of order.
    Docket Number: 24-010. Applicant: Massachusetts Institute of 
Technology, 77 Massachusetts Avenue, Cambridge, MA 02114. Instrument: 
Fiber Laser. Manufacturer: PreciLasers, China. Intended Use: The 
instrument will be used to study Potassium 40 atoms that are fermionic 
alkali atoms; their alkali electronic structure makes them straight-
forward to trap and manipulate using lasers. The potassium 40 atoms 
will first be cooled sympathetically by sodium 23 atoms, then 
transferred into a series of optical traps, which will use the lasers 
ordered from PreciLasers. The final optical trap will be a 2D square 
optical lattice, where additional optical potentials and magnetic 
fields will be applied, and the response of the atoms observed through 
a microscope.
    Docket Number: 24-012.Applicant: The University of Texas at Austin, 
BEG--JJ Pickle Research Campus, 10100 Burnet Road, Building 130, 
Austin, TX 78758.
    Instrument: Ocean Alpha SL20-Autonomous Survey Boat. Manufacturer: 
Ocean Alpha Group Ltd., China. Intended Use: According to the 
applicant, the instrument is intended to be used as an unmanned surface 
vehicle (USV) that is designed to survey the depths of inland waters 
where it is not accessible for UT Austin staff. USV will have 
complimentary use of the in-house airborne lidar system (Lecia 
Chiroptera-5) where lidar derived depths require verification. UT 
Austin staff will be able to deploy the USV from a shoreline, and 
control it remotely, with safety.
    Docket Number: 24-017.Applicant: State University of New York at 
Stony Brook, 100 Nicolls Road, 230 Admin Building, Stony Brook, NY 
11794. Instrument: 556 nm high power, narrow linewidth laser. 
Manufacturer: Shanghai Precilasers Technology Co., Ltd., China. 
Intended Use: According to the applicant, the instrument is intended to 
be used in a quantum optics apparatus using Ytterbium atoms in an 
ultrahigh vacuum environment. The experiment will laser cool and trap 
single Ytterbium atoms and interface them with single photons in an 
optical cavity. The importance is the long-lived clock states of 
Ytterbium atoms, as well as the hyperfine ground states, both of which 
are excellent to use as qubits in a quantum device and store quantum 
information for a long time.
    Docket Number: 24-018. Applicant: Harvard University, 17 Oxford 
Street, Cambridge, MA 02138. Instrument: Single Frequency Fiber Laser. 
Manufacturer: Shanghai Precilasers Technology Co., Ltd., China. 
Intended Use: According to the applicant, the instrument is intended to 
be used to explore methods of taking full control of the internal and 
external degrees of freedom of single diatomic molecules (calcium 
monofluoride, CaF) for various quantum applications. The interest is in 
quantum simulation of lattice-spin models using CaF molecules trapped 
in an optical tweezer array. To load CaF molecules into an optical 
tweezer array, they must be first laser slowed and laser cooled to very 
low temperature and high density. The laser cooling transition used 
here is one of the only two desired strong electronic transitions in 
CaF molecules that possesses a diagonal Frank-Condon factor which 
supports scattering many photons with reasonable number of repump 
lasers. This laser system will be used to perform the above work in a 
research laboratory in the Department of Physics at Harvard University. 
The research work enabled by this system is part of the training of 
graduate students, undergraduate students, and postdoctoral research 
fellows.
    Docket Number: 24-019. Applicant: Harvard University, Department of 
Physics, 60 Oxford Street, Cambridge, MA 02138. Instrument: Fiber 
Laser. Manufacturer Shanghai Precilasers Technology Co., Ltd., China. 
Intended Use: According to the applicant, the instrument is intended to 
be used for Ytterbium (Yb) atom's dipolar interaction. When Yb atoms 
excite their Rydberg states, there will be a strong dipolar interaction 
between the atoms. This interaction is also long-range. The main 
techniques used will be a) ultra-high vacuum techniques and b) laser 
stabilization techniques.The instrument will be used to educate 
undergraduate and graduate students.
