UltraFast Innovations (UFI) 1030nm Highly-Dispersive Ultrafast Mirrors with Reduced Thermal Lensing provide a GDD of -1000fs2 and low loss with negligible thermal effects. Thermal lensing can occur if an active gain medium is hotter along the beam axis than the rest of the medium, resulting in a transverse refractive index gradient. This can misalign the laser cavity and lead to different laser mode profiles and drifts in beam pointing. These mirrors are designed to provide a high degree of control over beam stability and feature reflectance >99.5% (P-polarization) between 1010 - 1050nm. At a design angle of incidence (AOI) of 5°, these mirrors maximize the number of reflections between a pair of ultrafast mirrors and allow for pulse compression while limiting thermal lensing. UltraFast Innovations (UFI) 1030nm Highly-Dispersive Ultrafast Mirrors with Reduced Thermal Lensing are ideal for intra-cavity applications, ultrafast high energy oscillators, and amplifiers such as Yb:YAG thin-disk laser systems. Please contact us if your laser system requires a custom size, wavelength, or pulse profile.
