Quasi-Continuous (QCW) Fiber Laser
The Quasi-Continuous (QCW) Fiber Laser combines some characteristics of both continuous wave and pulsed fiber lasers. It retains many advantages of the continuous fiber laser while also possessing some unique features and benefits.
Peak Power
0.01-50 ms Pulse Duration
Maximum Pulse Energy
Higher Cost-Effectiveness
High Peak Power and Single Pulse Energy
The QCW Quasi-Continuous Fiber Laser achieves high peak power output similar to that of a pulsed laser by specially designing and controlling the operating mode of the continuous fiber laser, while maintaining a certain level of average power to meet different application requirements. It can switch between continuous mode and pulsed mode, and in the pulsed mode, it achieves higher peak power at lower average power by limiting the laser duty cycle.
Application Advantages
High Energy Density and Strong Penetration
Under the same average power, the QCW Quasi-Continuous Fiber Laser can achieve greater peak power than the continuous fiber laser, resulting in higher power density. In material processing, such as welding of copper and aluminum alloy sheets, it can produce deeper penetration and better results.
Low Thermal Impact
Unlike continuous lasers that continuously act on materials, the QCW laser intermittently acts on materials, resulting in a smaller heat-affected zone and lower thermal input.
Flexible Modes
Can be set to pulsed mode or continuous mode, allowing for better adaptation to different processing needs. In pulsed mode, it can also minimize thermal impact on the component during cutting.
Application Cases
- Micro-hole Processing
- Precision Welding
- Ceramic Cutting
