Docket Number: 25-003. Applicant: California Institute of
Technology, 1200 E California Boulevard, Pasadena, CA 91125.
Instrument: Narrow-Linewidth Laser. Manufacturer: Shanghai Precilasers
Technology Co., Ltd., China. Intended Use: The instrument is intended
to be used for cooling of ytterbium atoms on the intercombination line
to reach temperatures lower than 50 micro-Kelvin using frequency
doubling of the high-power narrow-linewidth 1112 nm laser source. In
addition, the narrow-linewidth laser will be used for fluorescence
imaging as well as state preparation of the ytterbium atoms in one of
two desired spin states. For all of these applications, the narrow
linewidth as well as output power is crucial in terms of meeting the
experimental objectives. Justification for Duty-Free Entry: According
to the applicant, there are no instruments of the same general category
manufactured in the United States. Application accepted by Commissioner
of Customs: January 21, 2025.
Docket Number: 25-004. Applicant: University of Colorado JILA

80309. Instrument: High-power, narrow linewidth fiber laser.
Manufacturer: Shanghai Precilasers Technology Co., Ltd, China. Intended
Use: The instrument is intended to be used for two applications: (1) We
want to use it as a laser source that we will double to the wavelength
of 517nm, which will act as a novel transport system of ytterbium atoms
between ultra high vacuum chambers. (2) We want to use the laser itself
as a light source to trap ytterbium atoms--a novel alternative to our
current trapping lasers in the visible range of light. To meet the
needs of both, use cases, we require a narrow fiber laser combined with
a high power CW fiber laser amplifier. Justification for Duty-Free
Entry: According to the applicant, there are no instruments of the same
general category manufactured in the United States. Application
accepted by Commissioner of Customs: January 28, 2025.
Docket Number: 25-005. Applicant: University of Washington, 4300
Roosevelt Way NE, Roosevelt Commons West, Seattle, WA 98105-4718.
Instrument: Femtosecond lasers with ultrahigh power. Manufacturer:
ULTRONPHOTONICS CO., LTD., China. Intended Use: The instrument is
intended to be used to study very thin materials, just one atom thick,
called two-dimensional materials. These materials behave in very
special ways that are different from the everyday bulk materials. The
laser will also be used to study semiconductors to better understand
how they process information and energy. The ultimate goal is to
advance chip development and realize quantum computers, which can drive
breakthroughs in many areas, particularly, in artificial intelligence
(AI), that can also improve energy conversion efficiency and make
electric vehicle batteries safer. Justification for Duty-Free Entry:
According to the applicant, there are no instruments of the same
general category manufactured in the United States. Application
accepted by Commissioner of Customs: February 4, 2025.

Docket Number: 25-006. Applicant: Rice University, 6100 Main
Street, MS-61, Houston, TX 77005. Instrument: Narrow linewidth laser.
Manufacturer: Shanghai Precilasers Technology, Co., Ltd., China.
Intended Use: The instrument is intended to be used for the 3.4um laser
from Precilasers to drive an electronic transition across two
metastable energy levels in the singly ionized Ytterbium ion (Yb\+\).
The Yb\+\ion has a rich energy level structure owing to its electronic
configuration as a rare earth element. The \171\Yb\+\ ion (isotope=171)
consists of two ground state energy levels (\2\S<INF>1/2</INF> state)
that are robust to perturbations and are, therefore, used to encode a
bit of quantum information (qubit). Justification for Duty-Free Entry:
According to the applicant, there are no instruments of the same
general category manufactured in the United States. Application
accepted by Commissioner of Customs: February 20, 2025.

pass (FL-SF-2923-0.1-CW). Manufacturer: PreciLasers, China. Intended
Use: The instrument is intended to be used for driving the mid-infrared
optical transition in Strontium-88 atom arrays in optical tweezer
experiments. This mid-infrared transition in arrays will be used to
excite the 3P2-3D3 transition, enabling the study of quantum simulation
on the super-subradiance.
The objectives are to observe the evidence of super-subradiance in
the strontium-88 arrays, which are required to observe the lifetime
longer or shorter than spontaneous decay of single strontium-88 atom
(57 kHz). The mid-infrared transition will excite 2923 nm laser and
observe the lifetime of excited state via a state-detection method.
Justification for Duty-Free Entry: According to the applicant, there
are no instruments of the same general category manufactured in the
United States. Application accepted by Commissioner of Customs:
February 10, 2025.
