Ultrafast laser processing

Ultrafast lasers have emerged as a powerful tool for advanced manufacturing. Their short pulse duration, high peak power, and high repetition rate enable high-precision processing over large areas while minimizing damage to surrounding material.In this talk, I will present recent work from my research group on ultrafast laser-induced material ...

Femtosecond Lasers and Ultrafast Processes in Semiconductors

1986
Rapid progress has been made in the last few years1 on pico-second and femto-second lasers and related experimental techniques for studying ultrafast processes in various materials, including the dynamics of hot carriers in semiconductors. Of particular interest are GaAs and related compounds and structures, which are important for modern high-speed ...

Gigawatt Picosecond Dye Lasers and Ultrafast Processes in Semiconductor Lasers

1982
This thesis is a theoretical and experimental investigation of a gigawatt picosecond dye laser oscillator-amplifier system, and the application of that system to the study of ultrafast lasing and carrier dynamics in semiconductor lasers. Beginning with a review of traveling wave rate equations, nonlinear pulse propagation in a generalized two-level ...

Polarization Sensitive Ultrafast Laser Material Processing [PDF]

, 2016
In this thesis, I will concentrate on ultrafast laser interactions with various materials such as fused silica, crystalline silicon, amorphous silicon and nonlinear crystal.The first polarization sensitive ultrafast laser material interaction to be illustrated was second harmonic generation in lithium niobate by tightly focused cylindrical vector beams.
