Pulsewidth-Dependent Nonlinear Absorption of 1030-nm Ultrashort Laser Pulses in Polymethylmethacrylate

Key Points

Absorption varies nonlinearly based on pulse duration, showing different trends across specified ranges.
The absorption increases from 250 to 450 fs, then decreases from 450 to 1500 fs, stabilizing thereafter.
Assessment of laser pulse effects on polymethylmethacrylate provides insights into its optical characteristics.
Understanding these nonlinear effects may inform photonic and material applications in ultrafast optics.

Abstract

The effect of the duration of ultrashort laser pulses with a wavelength of 1030 nm on the process of their nonlinear absorption in polymethylmethacrylate is studied. It is found that the dependence of absorption on pulse duration is nonlinear, with an increase in the range from 250 to 450 fs, a decrease from 450 to 1500 fs, and insignificant changes after 1500 fs.
