Views：1892Everyone is familiar with laser processing, but can you distinguish the nanosecond laser, picosecond laser, femtosecond laser, etc. that you often hear?
➔ Let's first understand the conversion of time units
1ms (ms)=0.001s=10-3s
1μs (microsecond)=0.00001=10-6 seconds
If we understand the time unit, we will know that femtosecond laser is a kind of ultra-short pulse laser processing. In the past decade, ultra-short pulse laser processing technology has made rapid progress.
Laser processing: long pulse VS ultrashort pulse
Ultra-short pulse processing energy is injected into a very small action area very quickly, and the instantaneous high energy density deposition changes the electron absorption and movement mode, avoids the effects of laser linear absorption, energy transfer and diffusion, and fundamentally changes the interaction mechanism between laser and material.
Wide application of laser processing
Laser processing includes high power cutting and welding; The main uses of various laser processing methods for drilling, scribing, cutting, texturing, stripping, isolation, etc.
