Pulse lasers are devices that emit light in short bursts or pulses rather than a continuous beam. These pulses can last from femtoseconds (one quadrillionth of a second) to milliseconds, allowing for precise control over the energy delivered. This characteristic makes pulse lasers useful in various applications, including medical procedures, material processing, and scientific research. One common type of pulse laser is the Nd:YAG laser, which uses a neodymium-doped yttrium aluminum garnet crystal to generate high-energy pulses. Pulse lasers are also employed in LIDAR technology for mapping and surveying, as well as in laser cutting and laser engraving for manufacturing purposes.
