Professional 915nm 120W/130W Laser Igniter with Beam Expander: Features, Performance, and Safety

Published by Lilly Electronics

High-power infrared laser systems require more than raw output power. Stable operation, effective thermal management, controlled focusing, and appropriate safety features are all essential—particularly in demanding professional and industrial environments.

The Professional 915nm 120W/130W Laser Igniter with Beam Expander from Lilly Electronics combines high infrared output with adjustable optics, active cooling, and a compact aluminum housing. It is designed for knowledgeable professional users who require a stable optical source for specialized industrial laser systems.

What Is a 915nm Infrared Laser?

A 915nm laser operates in the near-infrared portion of the spectrum. Because most of its beam is invisible to the human eye, its apparent brightness must never be used to judge its actual power or safety.

This wavelength is commonly selected for specialized optical systems where infrared output, power stability, and efficient thermal performance are important. A properly configured 915nm source can support professional system integration, testing, research, and other controlled industrial applications.

Available 120W and 130W Output Options

The laser igniter is available in two output configurations:

• 120W

• 130W

The appropriate option depends on the requirements of the system in which it will be integrated. Factors such as operating conditions, duty cycle, optical configuration, cooling requirements, and the target material or process should all be evaluated.

More power is not automatically the better choice. Professional users should select the configuration that matches their equipment specifications and safety controls.

Beam Expander for Improved Optical Control

A beam expander is included to help modify the beam diameter for compatible professional applications. Expanding the beam may support better optical control within a properly engineered laser system.

Available beam-expander housing colors include:

• Silver

• Black

The product also includes an adjustable focusing lens, allowing trained users to configure the optics according to their system requirements.

Main Product Features

High-Power 915nm Infrared Output

The 915nm infrared source is available in 120W and 130W configurations for specialized professional applications requiring substantial optical output.

Stable Optical Performance

The system is designed to provide a stable optical pump source when operated under appropriate conditions and within its specified limits.

Built-In High-Speed Cooling Fan

High-power laser equipment generates significant heat. The integrated cooling fan helps manage operating temperature and supports more stable performance.

Temperature Protection Circuit

Built-in temperature protection provides an additional layer of system protection. Appropriate ventilation and operating procedures are still required.

Adjustable Focusing Lens

The included focusing assembly allows the optical configuration to be adjusted for compatible applications. Adjustment should only be performed by trained users with suitable protective equipment.

Aluminum-Alloy Housing

The compact aluminum housing offers durability while helping with heat dissipation.

Key-Switch Protection

A key switch helps restrict operation and reduces the possibility of unauthorized activation. The key should be removed and stored securely whenever the equipment is not in use.

Universal Power Compatibility

The included power system supports 100–240V AC input, making it suitable for use in many regions when the correct local plug configuration and electrical requirements are observed.

Important Laser Safety Information

This is a high-power optical device intended only for knowledgeable adult users in controlled professional environments. Improper operation can cause permanent eye injury, skin injury, fire, or property damage.

Before operating this equipment:

• Wear certified laser safety eyewear appropriate for the 915nm wavelength and output level.

• Never look directly into the beam or at reflected laser energy.

• Never point the equipment toward people, animals, vehicles, aircraft, or reflective surfaces.

• Prevent unintended access to the controlled operating area.

• Keep the equipment away from children and unauthorized users.

• Do not operate it near flammable or explosive materials.

• Inspect the equipment, power supply, cables, optics, and connections before use.

• Stop using the equipment immediately if any part appears damaged.

• Follow all applicable local laws and regulations governing high-power laser equipment.

Remember that a 915nm infrared beam may be largely invisible. The absence of visible light does not mean the laser is inactive or safe.

Basic Care and Maintenance

To support reliable performance:

• Keep optical surfaces clean with approved lens-cleaning materials.

• Avoid touching the lens directly.

• Keep threaded components and optical accessories securely attached.

• Ensure that ventilation openings remain unobstructed.

• Store the equipment in a clean, cool, and dry environment.

• Protect it from moisture, impact, dust, and direct sunlight.

• Inspect the system before every use.
