Ultrafast or ultrashort pulsed lasers have become integral in numerous industrial applications due to their high precision, non-thermal interaction with materials, and ability induce nonlinear absorption. These characteristics expanded use microfabrication, semiconductor processing, automotive engineering, biomedical fields. Temporal pulse shaping reduces laser durations, often shorter timescales than many physical chemical processes, enabling greater control. Meanwhile, spatial improves efficiency precision micro- nanofabrication applications. Advances optical parametric amplifiers (OPAs) chirped-pulse (CPAs) allowed for more refined temporal shaping, ensuring the preservation of peak power while achieving durations. Additionally, light modulators (SLMs) facilitated sophisticated beam which, when combined ultrafast lasers, supports like computer-generated holography nanoscale fabrication. developments underscore growing utility versatility both research contexts.
