Raycus Q-Switched Pulsed Fiber Lasers
Product Overview
 |
 |
Raycus Q-switched pulsed fiber lasers are industrial-grade light sources dedicated to marking and micro-machining. Adopting an all-fiber structure and proprietary Q-switching technology, they feature high peak power, high single-pulse energy, excellent beam quality, and high stability.
Covering a power range from 20 W to 100 W, these lasers are air-cooled, compact, and maintenance-free. They are widely used for marking, engraving, deep engraving, and precision micro-machining on metals and some non-metal materials, making them a cost-effective mainstream solution in the market for 3C electronics, hardware, auto parts, jewelry, molds, and other industries.
Product Features & Differences Between QS, QB, and Qmini Series
 |
 |
General Features
- All-fiber integrated design for high reliability, long lifetime, and maintenance-free operation
- High peak power and high single-pulse energy for high marking/engraving efficiency
- Excellent beam quality (M²<1.6) for fine lines and high contrast
- Wide repetition frequency range adaptable to various processes
- Air cooling and 24 VDC power supply for easy installation
- Support analog and RS232 control, compatible with mainstream marking cards
Key Differences: QS / QB / Qmini
-
QS Series (Standard) General-purpose mainstream model with standard spot size, pulse width, and repetition rate. Suitable for general marking, hardware engraving, daily hardware, and standard deep engraving.
-
QB Series (Enhanced) High-power / deep-engraving model with higher single-pulse energy and stronger deep-engraving capability. Suitable for molds, cutting tools, thick-workpiece deep engraving, and heavy-duty part marking.
- Qmini Series (Miniature) Ultra-compact, lightweight model for integrated applications. Suitable for portable marking machines, small desktop systems, and integrated equipment.
