Ultrafast laser research involves the study of lasers with extremely short pulse durations, typically in the femtosecond (10^-15 seconds) to picosecond (10^-12 seconds) range. These ultrafast lasers have revolutionized various fields such as physics, chemistry, biology, and materials science by enabling researchers to study phenomena that occur on very short timescales. Ultrafast lasers are used in a wide range of applications, including spectroscopy, microscopy, micromachining, and medical imaging. Researchers in this field aim to develop new laser sources, improve laser performance, and explore novel applications for ultrafast laser technology.
