A reliable & versatile tool for micromachining
FemtoLux is engineered for maximum reliability and seamless integration, supporting zero maintenance operation with innovative dry cooling. The tunable pulse duration from <350 fs to 1 ps and a broad AOM-controlled range of pulse repetition rates (single shot to 4 MHz) make it suitable for demanding micro-machining applications. Maximum pulse energy exceeds 300 μJ in single pulses and 750 µJ in burst mode, ensuring high ablation rates and throughput. Advanced control electronics allow simple integration with external controllers via REST API (Windows, Linux, and others), reducing integration time and resources.

Seamless user experience

• Easy integration – remote control using REST API via RS232 and LAN
• Reduced integration time – demo electronics available for laser control programming
• Easy and quick installation – no water, fully disconnectable laser head, end-user installable
• Easy troubleshooting – integrated detectors and constant system status logging
• No periodic maintenance required

Application fields

• Through glass vias (TGVs) manufacturing in glass
• Thin glass cutting
• Nitinol stent processing
• Microelectronics manufacturing
• Heat-sensitive polymer cutting
• Scribing of thick glasses
• Black/color marking of medical tools

Innovative “Dry” Cooling System
The FemtoLux laser employs a direct refrigerant cooling system, eliminating the need for bulky water chillers and associated maintenance. The refrigerant circulates from a PSU-integrated compressor and condenser to a cooling plate via armored flexible lines. The system is hermetically sealed, maintenance-free, and offers high cooling efficiency with >45% lower power consumption compared to water cooling.

Direct refrigerant cooling system features

• Military-grade reliability
• Permanently hermetically sealed system (>90,000 hour MTBF)
• No maintenance
• High cooling efficiency
• >45% lower power consumption than water cooling
• Compact and light

Simple & reliable cooling plate attachment
The cooling plate is detachable from the laser head for convenient installation. The cooling equipment is integrated with the power supply unit into a single 4U rack-mounted housing (total weight: 15 kg).

Pulse-on-Demand (PoD) Option

• Jitter lower than 20 ns ensures consistent and equidistant pulse spacing for high-speed micromachining
• Adjustable repetition rate for processing complex geometries
• Faster processing speeds and increased productivity

PoD enables the laser to fire pulses only when required, improving efficiency, accuracy, and quality in micromachining. This feature is essential for high-speed, high-precision applications where equidistant pulse spacing is critical.

GHz Burst Option

• Any desired intra-burst PRR can be achieved independently from the master oscillator
• Identical pulse separation inside GHz bursts
• Short- and long-burst formation modes (0.5–10 ns for short, 20–500 ns for long bursts)
• MHz+GHz burst mode
• Adjustable amplitude envelope of GHz bursts
• No pre/post pulses in GHz burst
• Ultrashort pulse duration maintained inside bursts

Patent-pending all-in-fiber active fiber loop (AFL) technology enables flexible burst formation and operation in single-pulse, MHz burst, GHz burst, and MHz+GHz burst modes.

Laser control application
Ekspla Control Application allows routine operation control via LAN or RS-232, with self-adaptive software compatible with multiple systems and platforms.
