The Association of Universities for Research in Astronomy; 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 1966 (Pub. L. 89-
651, as amended by Pub. L. 106-36; 80 Stat. 897; 15 CFR part 301). On 
January 24, 2023, 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, 88 FR 4155, January 24, 2023 (Notice). 
We received no public comments.
    Docket Number: 23-004. Applicant: The Association of Universities 
for Research in Astronomy (AURA), 950 N Cherry Avenue, Tucson, AZ 
85719. Instrument: (4) Laser Launch Telescopes. Manufacturer: Officina 
Stellare, S.p.A., Italy. Intended Use: The

instrument is intended to be used to study the creation of four 
artificial stars for the purpose of conducting Adaptive Optics 
scientific observations. Existing and upcoming next generation optical 
telescopes require highly reliable 589 nm high power lasers--to 
generate so-called Guide Star Lasers--for the implementation of 
adaptive optics facilities. The four Laser Launch Telescopes will be 
used to project these laser beacons to create a constellation of 
artificial laser guide stars on top of the telescope. The experiments 
to be conducted: The four Laser Launch Telescopes used as an accessory 
to the Adaptive Optics system GMAO (currently in development) will 
propagate a constellation of artificial guide stars to measure the 
incoming wavefront. The objectives pursued during the investigations 
will be used on selected nights for selected astronomical targets in 
hopes of attaining better scientific data.
