Pulsed lasers are lasers that emit high-intensity pulses of light in a very short duration, typically in the nanosecond to femtosecond range. These lasers are used in a wide range of applications, including materials processing, medical procedures, telecommunications, and scientific research. Pulsed lasers are highly versatile and can be used for precision cutting, welding, drilling, and marking of materials. They are also used in medical procedures such as laser eye surgery and tattoo removal. In scientific research, pulsed lasers are used for spectroscopy, imaging, and studying ultrafast processes. Pulsed lasers operate by generating short bursts of light through processes such as Q-switching or mode-locking. This allows them to deliver high peak powers while maintaining relatively low average powers, making them ideal for applications that require intense but brief bursts of energy. Overall, pulsed lasers play a crucial role in many cutting-edge technologies and applications, making them a key area of research and development in the field of laser technology.
