Laser-Induced Damage in Doped and Undoped Fluorozirconate Glass

Source

Results of laser-induced damage studies in doped and undoped fluorozirconate (FZ) glass in the system of ZrF4-BaF2-LaF3-AlF3 are reported. Measurements were made at 1.06 and 0.53 μm for pulsewidths of 45 psec and 20 nsec (FWHM), respectively. The breakdown thresholds are significantly reduced for material doped with Cr, Mn, Ni, and Nd. The decrease in breakdown thresholds at the fundamental wavelength (λ) for the doped material was found to be roughly proportional to the linear absorption of the specimen at the second harmonic (λ/2). This suggests that two-photon absorption (2PA) is instrumental in initiating damage in the doped specimens.
