Measurement of wavefront distortions resulting from incidence of high-power 2 μm laser light

Wavefront distortions induced in various silica samples by a 2 μm thulium fiber laser were measured. Absorption of silica at 2 μm makes a full characterization of thermal lensing critical for high power applications.
