Peak Power
Pulse Duration
Pulse Energy
Quasi-continuous wave (QCW) fiber lasers utilize relatively long pulses of high laser power to achieve processing results similar to that of continuous wave (CW) lasers with lower average power.
Quasi-CW pulses provide peak power up to 10X average power and are able to offer up to hundreds of joules of pulse energy.

Quasi-continuous wave (QCW) fiber lasers utilize relatively long pulses of high laser power to achieve processing results similar to that of continuous wave (CW) lasers with lower average power.
Quasi-CW pulses provide peak power up to 10X average power and are able to offer up to hundreds of joules of pulse energy.
Higher peak powers increase the capabilities of QCW fiber lasers to couple with metallic and non-metallic surfaces at a lower average power. Compared to high-power CW lasers, QCW lasers are often more cost-effective and productive for applications requiring low heat input or high pulse energy.
Featuring multiple wavelengths and single-mode, multi-mode, or dual-beam options, QCW lasers offer flexible operation for a broad variety of applications including metal and non-metal processing and medical applications.
Whether you need a custom laser solution or just want to learn more from our global team of laser experts, we're here to help.
