The term "Waiting periods" in this section deal with the time that the court requires must pass from the time the divorce is filed, and the time that the Judge signs your divorce decree.
Alaska law requires that thirty (30) days elapse from the filing of the Complaint and summons or Answer and Waiver before a final judgment of divorce be entered. If your spouse signs the Alaska "Entry of Appearance and Waiver" immediately after you file the complaint then you can divorced in as little as 30 days.
