Pulsed laser source VLM/VLR

nanosecondquasi-continuous wavefiber

Overview
Utilizing laser pulses measured in billionths of a second, green and visible wavelength nanosecond fiber lasers provide precise material interaction for microprocessing and non-metal applications. IPG fiber laser technology delivers modular and rack-mount solutions with configurable wavelengths and pulse durations to support industrial integration and production needs.

Applications

• High-speed micromachining and precision cutting of polymers, glass and ceramics
• PCB cutting and marking, resistor trimming, scribing
• Marking of transparent materials and delicate surfaces
• Drilling, texturing and microstructuring of non-metal materials including silicon and OLED substrates
• Copper additive manufacturing and laser sintering
• Wafer and OLED annealing, solar cell processing (PERC contact opening, selective emitter)
• Medical, scientific and advanced manufacturing applications

Product highlights

• Wavelength coverage across green and visible: typical 517–642 nm (varies by module/model)
• Average power scalable from low-power families up to 1 kW for quasi-CW/high-power variants
• Pulse durations from ~1 ns up to 1000 ns depending on family; burst and QCW options available
• High peak power with short pulse duration for reduced heat-affected zone and precise interaction
• Modular and rack form factors with configurable pulse energy, repetition rate and wavelength

Marking & Micromachining
The short visible wavelengths and nanosecond pulses produce small heat-affected zones and efficient absorption in many non-metal materials, improving edge quality and feature resolution for marking, cutting, scribing and copper sintering processes.

Notes
Available product families include low-power pulsed (10–30 W), mid-power (50–75 W), higher-power (75–100 W), quasi-CW/high-power models and visible nanosecond modules. Some specifications are preliminary; IPG provides custom configurations on request and regional availability may vary.
