Abstract

An aerothermal modeling framework was developed for the entire TMT International Observatory Laser Guide Star Facility, consisting of several standalone conjugate heat transfer models: laser head, laser bench array, optical path pointing arrays, beam transfer duct, top end including the laser telescope assembly, and several electronics cabinets, resolving all interior components. The primary goals were to evaluate the focus error from the thermal lens deformation, to evaluate beam jitter from the optical path difference maps along the beam path, and to obtain the temperature of all exterior surfaces. The framework provided performance sensitivity to specific inputs/assumptions and lead to improved design that meets performance requirements.
