NuQ Marking laser

Product catalog summary

Overview
This document provides a comprehensive review of the optical and electrical design of Nufern's high-performance pulsed fiber marking lasers, specifically focusing on 20W, 30W, and 50W models. The document highlights the competitive advantages of these lasers, including faster turn-on times, better beam quality, highest peak power, and stable output.

Optical Design and Results
The optical design emphasizes high beam quality with a Gaussian pulse shape, which ensures the highest peak power and fastest turn-on times. The lasers are designed to produce precise and repeatable marks on sensitive materials, eliminating over-burn in critical applications. The Gaussian-like pulse shape maximizes material vaporization, resulting in minimal dross and re-cast.

Electrical Design and Results
The electrical design focuses on delivering more marking power per watt with excellent pulse-to-pulse energy stability. The 20W unit demonstrates a 1.7% energy variation at 20 kHz and a 2.3% variation at 80 kHz, ensuring high mark repeatability. The lasers offer fast turn-on and turn-off times, with minimal leakage, enhancing marking speed and contrast.

Performance and Specifications
The lasers operate over a broad temperature range, providing stable performance and high long-term reliability. The document includes graphical data illustrating output power adjustability and energy per pulse across different power settings and frequencies. The lasers yield ultra-fine, crisp marks with high 90% circularity and single-mode beam quality.

Comparative Analysis
Nufern's lasers are compared against competitors, showing superior performance in terms of no ghost marks, better finish for deep engraving, and highest energy density for deep marks. The document highlights the commercial value and application ease of these lasers, encouraging users to make the switch to Nufern's technology.

1. Long IPG turn off time results in two aftermaths: 2. The galvo head may need to decelerate for a long time, resulting in low marking speed. 3. When galvo head delay is set to short for high marking speed, the slow turn off pulse train leaves a irregular turn around ghost trace and sacrifice the marking contrast. Marking Results
