STJ Pulsed Fiber Lasers
- Flexible & independent control of pulse width & frequency
- Selectable pulse shape
- High repetition frequency
- No laser leakage
PRODUCT DESCRIPTION
STJ series fiber laser adopts MOPA (Master Oscillator Power Amplifier) structure, diode laser as seed light, and fiber based power amplification. This laser integrates independence adjustment of pulse width and frequency, to make sure a constant pulse energy output, which provides a good combining solution to the requirements of high power laser source and high marking speed.
The extremely flexible pulse width and frequency adjustment, which plays a significant impact on colour formation, enables colour or silver shining marking on stainless steel.
Features:
· Flexible & independent control of pulse width & frequency
· Selectable pulse shape
· High repetition frequency
· No laser leakage
Applications:
· Marking / Colour marking
· Ablation
· Cutting
· Drilling
· Scribing
· Soldering
· Trimming
· Engraving
