3. Modes of Laser Operation (Light Emission Control)
These define how laser “light” behaves for different use cases:
- CW (Continuous Wave) – Constant beam, better for speed and deep welds.
- Pulsed Mode – Short, intense bursts of energy for precise and heat-sensitive welding.

Here’s a comprehensive and professional overview of all key concepts behind Modes of Laser Operation as used in Sigma Laser’s “Light” series, including:
- ✅ Clear explanation
- 📊 Best practices
- ❓ FAQs
- 🔁 Comparison to competing technologies
What Are Laser Operation Modes?
In laser welding, the mode of operation defines how laser energy (light) is emitted. Sigma Laser systems, especially the “Light” series (Sidanus Light, Sirius Light, Siega Light), support two main operating modes:
1. Pulsed Mode (Pulsbetrieb)
The laser emits short bursts (pulses) of high energy.
- Pulse duration: Typically 0.5–50 ms
- Pulse energy: Up to 170 J
- Pulse peak power: Up to 13 kW
🔧 Best for:
- Welding thin materials
- Heat-sensitive or brittle alloys (e.g. titanium, Inconel, tool steels)
- Precision seam welding with minimal heat input
Sigma Advantage:
✔ Super Pulse Technology (SPT) – proprietary software that modulates the pulse for smoother, crack-free welds and enhanced energy efficiency.
2. Continuous Wave (CW Mode)
The laser emits a constant, uninterrupted beam of energy.
- Power range: 300–450 W (in fibre systems)
- No distinct pulses
🔧 Best for:
- High-speed welds
- Deep penetration
- Welding large components (e.g. thick aluminum, steel sheets)
Sigma Advantage:
✔ Efficient beam shaping & cooling even in CW mode using TLC and modular optics.
Application Type |
Recommended Mode |
Why |
Delicate or heat-sensitive parts |
Pulsed |
Less heat distortion, high control |
Micro-welding (0.05 mm+) |
Pulsed |
High peak energy in short bursts |

Continuous energy = faster throughput |
Welding special alloys (e.g. Inconel, Ti) |
Pulsed + SPT |
Custom pulse shaping improves results |
Repairing large molds or dies |
CW or Pulsed |
Depends on access and depth |
Always select the laser mode based on material, joint type, speed, and heat tolerance.
❓ Frequently Asked Questions (FAQs)
Only systems like Simass and Fibre series support both. “Light” systems are pulsed Nd:YAG lasers and not CW.
Pulsed mode offers high peak energy with low heat input, essential for crack-prone or small components.
A Sigma-exclusive feature that modulates pulse shape to fine-tune heat flow. Especially effective for brittle or high-temp alloys.
Not necessarily. CW delivers sustained energy, but pulsed lasers can reach higher peak powers in short bursts.
Use pulsed mode + SPT, reduce pulse duration, or use appropriate focus settings with beam expanders.

The “Light” series by Sigma Laser is strategically positioned as a high-performance, compact, and modular solution for industrial laser welding based on lamp-pumped Nd:YAG technology. Unlike commodity fibre laser solutions, the “Light” systems deliver superior pulse peak power, better control over metallurgical results, and modular scalability—tailored to professionals in tool repair, aerospace, medical devices, and mold making.
Best Practice Strategy for Positioning the “Light” Series
1. Target Industries
- Aerospace: High-precision repair in hard-to-reach areas (Siega Light).
- Automotive: Mold & die welding, tool repair.
- Medical Devices: Clean, fine welding with high-quality seams.
- Shipbuilding: On-site repair with mobile Sirius Light.

❓ FAQs – Sigma Laser “Light” Series
The main advantage is its high pulse peak power, which enables superior results on difficult materials and reduces the need for post-processing—ideal for critical industries like aerospace and medical technology.
“Light” systems use lamp-pumped Nd:YAG lasers, which offer higher pulse energy and peak power, whereas fibre lasers are better suited for continuous wave operation with lower maintenance. Sigma also offers both, but “Light” is best for precision pulsed welding tasks.
Yes. The systems are built with a modular concept, meaning power levels, axes, and control software (like Sigomatic or SPT) can be upgraded over time.
Yes. Sirius Light and Siega Light are designed for on-site repair and mobile operation, including work on components weighing up to 25 tons.
With Sigma’s Twin Lamp Cavity (TLC) technology, the lifetime of flashlamps is significantly extended compared to traditional one-lamp systems. Routine maintenance ensures long-term use.
- Sidanus Light: For precision shop-floor work (stationary).
- Sirius Light: For mobile welding of large, heavy parts.
- Siega Light: For compact environments and difficult access points.
Summary
“Light” in Sigma Laser’s ecosystem is continuously optimized through:
- Pulse energy (Joules)
- Peak power (kW)
- Repetition rate (Hz)
- Pulse duration (ms)
- Focus diameter (mm)
Sigma Laser have strong modular systems, TLC and SPT that makes real differences.
