Alaska Stat. § 12.50.020

(a) If a person in a state which by its laws has made provision for commanding persons inside its borders to attend and testify in criminal prosecutions or grand jury investigations commenced or about to commence in this state as a material witness in a criminal action pending in a court of record of this state, or in a grand jury investigation which has commenced or is about to commence, a judge of the court may issue a certificate under the seal of the court stating these facts and specifying the number of days the witness will be required. The certificate may include a recommendation that the witness be taken into immediate custody and delivered to an officer of this state to assure attendance in this state. This certificate shall be presented to a judge of a court of record in the county or judicial district in which the witness is found. This order of a court in the other state delivering custody of a witness to an officer of this state shall be sufficient authority to an officer of this state to take the witness into custody and hold the witness until discharged by a court of this state.

(b) If the witness is subpoenaed to attend and testify in this state the witness shall be tendered a sum equivalent to the cost of air fare round trip passage on a certificated carrier or such prepaid passage and reasonable incidental travel allowance for going to and from airports plus $20 per day for each day that the witness is required to travel and attend as a witness. A witness who has appeared in accordance with the provisions of the subpoena shall not be required to remain within the state a longer period of time than the period mentioned in the certificate, unless otherwise ordered by the court. If the witness, after coming into this state, fails without good cause to attend and testify as directed in the subpoena, the witness shall be punished in the manner provided for the punishment of any witness who disobeys a subpoena issued from a court of record in this state.
