Femtosecond Nonlinear Optical Properties of Heavy Metal Borate Glasses Studied Using Z-scan Technique

摘要

Inorganic glassy materials are most suitable for fabricating active as well as passive photonic devices. In view of this, the glasses with composition (mol %) 10La_2O_3-30HMO-60B_2O_3 (HMO = PbO, Bi_2O_3) were fabricated by melt quenching method. The nonlinear optical (NLO) properties have been investigated through standard Z-scan method at 800 nm using 150 femtosecond (fs) laser pulses fired at a rate of 80 MHz. The NLO attributes obtained from our studies clearly demonstrate the studied glasses are useful for optical limiting applications in the protection of eyes and sensitive photonic devices from damage caused due to intense laser radiation.
