High Power and Precision

Delivering up to 20 W average power and 130 µJ pulse energy, the laser ensures efficient energy delivery for high-throughput micromachining and cutting applications. Its M² < 1.2 beam quality provides consistent, Gaussian-like performance.

Adjustable Pulse Parameters

Users can fine-tune pulse duration (400 fs – 2 ps) and repetition rate (100 kHz – 1 MHz) to match diverse material properties and application needs — from fine ablation to deep cutting.

Maintenance-Free Operation

The passive air-cooling system eliminates the need for water chillers, reducing maintenance costs and simplifying integration. Its compact, sealed design ensures long-term reliability and stability in industrial environments.

Dual-Wavelength Capability

With an optional SHG module, the system delivers both infrared (1030 nm) and green (515 nm) outputs, expanding processing capabilities across metallic, ceramic, and transparent substrates.

Exceptional Beam Stability

Long-term testing demonstrates <0.15% RMS power fluctuation over 60 hours and <6 µrad beam pointing stability, ensuring repeatable precision in extended industrial operations.

Compact and Efficient Design

The lightweight laser head and low power consumption (≈300 W post-warm-up) make the system easy to integrate into production lines or laboratory setups, maximizing space and energy efficiency.

Turn-Key Integration

Ready to operate out of the box, the system includes USB and CAN interfaces for seamless automation and remote control. Combined with United Spectrum Instruments’ technical support, the LitiLit 20W laser offers a complete, high-reliability solution for industrial and scientific innovation.

Material Microprocessing

The 20W femtosecond laser enables high-precision micromachining of metals, polymers, and ceramics with minimal thermal effects. Its ultrashort pulses eliminate heat diffusion, ensuring clean cuts and smooth edges ideal for manufacturing microcomponents and sensors.

Semiconductor and Electronics

In semiconductor fabrication, the laser’s stability and pulse control make it suitable for wafer scribing, drilling, and thin-film patterning. The negligible heat-affected zone ensures no microcracks, maintaining the integrity of delicate electronic structures.

Display Manufacturing

Used in OLED and LCD production, the laser performs precise ablation and surface patterning for transparent conductive films. Its sub-micron accuracy guarantees defect-free displays and improved production yields.

Battery Production

The laser’s high pulse energy supports electrode cutting and laser welding of battery components. These processes enhance electrical conductivity and mechanical reliability in energy storage systems, including EV battery packs.

Medical and Ophthalmic Applications

In ophthalmology and biomedical device fabrication, the laser’s femtosecond precision allows non-invasive, clean incisions without tissue damage. It’s also ideal for marking surgical instruments and implants with permanent, corrosion-resistant identifiers.

Stainless Steel Marking

The 515 nm (green) output enables black and colour marking on stainless steel and titanium surfaces. These markings are corrosion-proof and remain stable under high wear conditions — perfect for medical, aerospace, and industrial identification applications.
