One, the characteristics of different
1, picosecond laser: with picosecond ultra-short pulse width, repeat frequency adjustable, pulse energy and other characteristics.
2, traditional laser: compared with ordinary light source monochromatic, directional good, higher brightness.
Two, different characteristics
1, picosecond laser: repetition frequency of 100 kHz to 1000 kHz, excellent beam quality M?<1.3.
2, traditional laser: all of its light waves are synchronized, the whole beam of light is like a "wave train".
Three, the role of different
1, picosecond laser: picosecond pulse width can be compared to the time of electro-optical relaxation, short enough to "cold" ablation of the material.
2. Conventional lasers: pressure effect, electromagnetic field effect and biostimulation effect.
