What is the difference between picosecond laser and traditional laser?

First, the characteristics are different.

1, picosecond laser: It has the characteristics of picosecond ultra-short pulse width, adjustable repetition frequency and high pulse energy.

2. Traditional laser: Compared with ordinary light source, it has good monochromaticity and directionality and higher brightness.

Second, the characteristics are different.

1, picosecond laser: repetition frequency 100 kHz to 1000 kHz, excellent beam quality m? & lt 1.3。

2. Traditional laser: all its light waves are synchronous, and the whole beam of light is like a "wave train".

Third, the roles are different.

1, picosecond laser: the picosecond pulse width can be compared with the electro-optical relaxation time, which is short enough to "cool" the ablation material.

2. Traditional laser: pressure effect, electromagnetic field effect and biological stimulation effect.
