What is a Pulsed Laser? Working Principle and Application Analysis

I. Working Principle of Pulsed Lasers

A pulsed laser consists of a laser medium, an optical resonator, and a pumping system. The pumping system injects energy into the laser medium, causing it to reach an excited state. When the excitation threshold is reached, the medium emits a short burst of light, which is the pulsed laser output.

II. Characteristics of Pulsed Lasers

Pulsed lasers are characterized by short pulse duration, high energy density, high power, and high repetition rate. Due to its high energy density and short pulse duration, pulsed lasers are widely used in medical, industrial, and communication fields.

III. Application Areas of Pulsed Lasers

1. Medical field: Pulsed lasers can be used in ophthalmic surgery, cosmetic dermatology, dental treatment, and other areas.

2. Industrial field: Pulsed lasers can be used in material processing, precision machining, welding, and other areas.

3. Communication field: Pulsed lasers can be used in fiber optic communication, lidar, and other areas.

IV. Conclusion

In general, pulsed lasers are a very important type of laser, widely used in medical, industrial, and communication fields. By deeply understanding the working principle and characteristics of pulsed lasers, we can better master their application technology and promote their development.
