Paper Abstract

The Gound-Based FEL Technology Integration Experiment's high power laser requires a beam director-dome window to protect the optics from dust accretion and reduce the optical aberrations occurring in the air interface between the dome interior and exterior. One half of the dual aerocurtain designed for this purpose is heated 18 C above ambient temperature, while the other is not heated; this results in the development of two mixing zones, (1) between the heated and unheated halves, and (2) between the latter and the room air. This aerocurtain configuration is shown to reduce the Strehl ratio loss through the window to several percent.
