Quasi-continuous Fiber Lasers Usher in a Golden Period of Development

Introduction:

 Quasi-continuous (QCW) fiber lasers can operate in both pulsed and continuous (CW) modes, so a single laser can handle a variety of processing tasks that previously required two different lasers.

There are many reasons for businesses to use quasi-continuous (QCW) fiber lasers, such as fiber lasers combining the drilling and welding advantages of a pulsed Nd:YAG laser with the cutting capabilities of a CO2 laser. The combination of these processing capabilities cannot be achieved with conventional technology, so in the past many companies had both CO2 lasers and Nd:YAG lasers to address a wider range of processing needs and applications.

QCW fiber lasers can operate in both pulsed and continuous (CW) modes, so a single laser can handle a variety of processing tasks that traditionally required two different lasers.

Fiber lasers are solid-state lasers with continuous fiber optic connections that are permanently sealed against dust and dirt, and contain no moving parts.

Today, tens of thousands of fiber lasers are used 24/7 in countless industries and fields. These laser systems are rapidly replacing the role of Nd:YAG lasers and CO2 lasers in many materials processing applications. In addition, companies are replacing old lasers on existing production lines while ensuring that downtime losses in their existing equipment are minimized.

Why choose QCW fiber lasers?

Quasi-CW fiber lasers are now part of modern manufacturing plants.

Such lasers can operate in both continuous and high peak power pulsed modes. Unlike conventional continuous continuous (CW) lasers, whose peak and average power are always the same in CW and CW/modulation modes, QCW lasers have 10 times higher peak power than average power in pulsed mode.

Thus, this enables the generation of microsecond and millisecond pulses with high energy at repetition rates from tens of hertz to several kilohertz, and achieves average and peak powers of several kilowatts.
