Introduction

With precision manufacturing demands on the rise, traditional laser processing technology is challenged in terms of accuracy, efficiency and material adaptability.
Nanosecond laser,Picosconde laser and femtosecond laser technology are three key aspects of pulsed lasers, and each has specific benefits in various sector applications.

By adjusting pulse length from nanoseconds to femtoseconds, light or X-ray sources generated by this class of lasers can enable high precision material processing with minimized heat dissipation and enhanced processing quality.

In this review, we will elaborate on the differences among nanosecond laser, picosecond laser and femtosecond laser, and introduce their work principles, advantages, applications, etc., so that you can find the right laser solution.

What Is a Nanosecond Laser?

Pulsed laser- A nanosecond laser is a type of pulsed laser that emits pulses of duration on the order of a few nanoseconds (10⁻⁹ s).

Nanosecond lasers have a mature tech and high peak power, which makes it an best sellers for industrial marking and materials processing.

What Is a Picosecond Laser?

A picosecond laser is an ultrashort pulse laser, which pulse duration lies in the scale of picoseconds (10⁻¹² s) in the time domain.

Picosecond lasers have shorter pulse durations than nanosecond lasers and therefore they have less exposure time on the surface of the workpiece, which means less heat build-up.

This allows for use in ultra precision applications with good surface quality.
