MAX QCW fiber laser

MFSQ Series Quasi-Continuous Wave (QCW) Fiber Laser Product Introduction

The MFSQ series of quasi-continuous wave (QCW) fiber lasers offers peak power up to 10 times the average power in pulsed mode. Through a modulation module, the continuous output is cut into high-duty-cycle pulse sequences, achieving millisecond-level long pulse width output while maintaining the high beam quality (M²≤1.1~1.3) of fiber lasers. This makes them ideal light sources for welding highly reflective materials, precision machining of thin plates, and connecting heat-sensitive devices.

The MFSQ series covers power levels from 50/500W to 1500/15000W. The four main models—MFSQ 150/1500W, 300/3000W, 450/4500W, and 600/6000W—form a complete product matrix. Employing a dual air-cooling/water-cooling system, they are widely compatible with existing production lines and can directly replace traditional lamp-pumped YAG lasers, supporting precision machining upgrades in high-end manufacturing fields such as new energy, 3C electronics, and medical devices.

Features of MFSQ series quasi-continuous (QCW) fiber laser technology

Compared to international brands such as IPG Photonics and nLight, Chuangxin's MFSQ series, based on a vertically integrated domestic supply chain system, offers a significant cost-performance advantage while maintaining equivalent optical performance (beam quality M²≤1.3, electro-optical conversion efficiency>30%). IPG and nLight adopt a standardized product strategy, while Chuangxin offers deep customization capabilities tailored to the characteristics of China's manufacturing industry:

1. Selectable fiber core diameter: Supports customization of multiple output fiber core diameters such as 14μm, 30μm, 50μm, 100μm, and 200μm to meet the spot diameter requirements of different application scenarios (IPG typically provides a standard configuration);

2. Waveform editing function: Built-in 16 sets of programmable waveform storage, supports gradient pulse shaping, which can avoid "weld tube" or porosity defects at the start/end of welding (compared to IPG which requires an external pulse shaper);

3. Dual versions with air and water cooling: Models such as the MFSQ 150/1500W offer a compact air-cooled design, eliminating the need for an external chiller, making it more suitable for handheld welding and flexible deployment on production lines (IPG in the same power range is mostly water-cooled).

IPG has a technological advantage in the ultra-high power range (such as above 15000W) and possesses high-end features such as adjustable AMB beam mode. Chuangxin achieves a more compact size (overall dimensions 950×482.6×193.2mm) and more flexible interface protocols in the mid-power range (150-600W average power) through modular design, making it more suitable for integration into automated production lines.
