Coherent high-power fiber laser EDGE FL1.5

Coherent's EDGE FL1.5 is a high-power continuous wave (CW) fiber laser optimized for industrial cutting, welding and additive manufacturing applications. The following is a detailed introduction to its core functions and features:

1. Core functions

(1) Industrial-grade material processing

Metal cutting

Suitable for efficient cutting of carbon steel, stainless steel, and aluminum alloys (thickness up to 30mm+).

Beam quality (M² < 1.1) ensures smooth cuts and reduces the need for subsequent processing.

Welding applications

Keyhole welding is suitable for power batteries and automotive parts (such as motor housings).

Can be used with a swing welding head to achieve wide weld processing.

Additive manufacturing (3D printing)

Used for metal powder cladding (DED/LMD), such as aerospace component repair.

(2) High dynamic processing

Supports high-acceleration motion systems (such as robots, galvanometers), suitable for complex trajectory processing (such as curved surface cutting).

2. Key Features

(1) High power and excellent beam quality

Power output: 1.5 kW (continuously adjustable, 100% duty cycle).

Beam quality: M² < 1.1 (near diffraction limit), small focused spot diameter, high energy density.

(2) Flexibility and integration

Fast modulation response: supports analog/PWM modulation (frequency up to 50 kHz), adapting to high-speed processing needs.

Industrial interface: standard EtherCAT, Ethernet/IP, compatible with PLC and automation control systems.

(3) Reliability and easy maintenance

All-fiber design: no risk of optical component misalignment, resistant to vibration and dust.

Intelligent monitoring: real-time monitoring of temperature, power, cooling status, fault self-diagnosis.

Low maintenance cost: no consumables (such as lamp tubes for lamp-pumped lasers), life span >100,000 hours.

(4) Energy saving and high efficiency

Electro-optical efficiency >40%, more than 50% energy saving compared to traditional CO2 lasers.
