Ultrashort pulses refer to very short bursts of electromagnetic radiation, typically on the order of femtoseconds (10^-15 seconds) to picoseconds (10^-12 seconds) in duration. This field of research primarily focuses on generating, manipulating, and utilizing these extremely short pulses of light for various applications in science and technology. Ultrashort pulses have revolutionized multiple areas of research, including ultrafast spectroscopy, laser micromachining, and nonlinear optics, due to their ability to capture and study ultrafast phenomena in a wide range of materials and systems. Additionally, ultrashort pulses play a critical role in advancing technologies such as ultrafast communications, medical imaging, and precision manufacturing.
