Alaska has not opted out of the federal exemptions. Alaska
Stat. § 09.38.55 can be confusing on this point (“In a
proceeding under [Title 11] only the exemptions in [specified
Alaska provisions] apply.”). But that language is not sufficiently
specific to operate as an opt-out.
In re Tinkess, 459 B.R. 76
(Bankr. D. Alaska 2008).

So, if this state is the applicable state (as determined by the
method stated on the home page of this site), the federal
exemptions may be used regardless of whether the debtor is
or is not a resident  of this state on the date of filing
bankruptcy.
