Ultrashort pulse (USP) lasers emit pulses that last from few femtosecond to 10 picoseconds. Once they impinge on the target, they cause an explosion of the material without heat production.
The athermic laser material interaction guarantees a precision with a sub- micrometer resolution.
Thanks to the extremely high peak intensity, USP lasers enable high precision crack-free micromachining on a huge variety of different materials such as metals, ceramics, composites and glasses.
USP lasers are increasingly used in the manufacturing industry for high precision cutting, drilling, milling, engraving, marking and cleaning.
SINGLE PULSE MODE
emission in the MHz repetition rate of evenly spaced ultrashort pulses
Complex design with CPA and multistage amplifiers
Cumbersome footprint that makes integration more difficult
Pretty slow machining speed that can not be increased
Small number of adjustable parameters limit optimisation
GHZ BURST MODE
ultrashort pulses at the GHz repetition rate are clustered in bursts
Innovative proprietary design with only one amplification stage and no CPA
Innovative proprietary design saving up to 60 % of space
Enhanced machining speed without compromising precision
Fully tailorable burst parameters for a fine optimisation
Traditional USP lasers, widely employed for micromachining, emit individual high-energy pulses at repetition rates up to 10 MHz, excelling in precision but lacking in machining speed.
Enter FEMTOFLASH – a game-changer. Instead of relying on single pulses, FEMTOFLASH emits bursts of high-frequency pulses. In this groundbreaking technology the energy is distributed over many pulses that are clustered in bursts and the pulse frequency is increased a thousandfold (GHz level), thereby significantly enhancing machining speed.
Unlike the high energy of single pulses, FEMTOFLASH maintains the energy of each pulse within the burst just above the machining threshold (few μJ). This strategic energy management in burst mode eliminates surplus energy, preventing detrimental effects that could compromise machining quality. The result? FEMTOFLASH seamlessly combines precision and speed, marking a leap forward in efficient micromachining.
Unlike common USP lasers for material processing that have a complex structure of at least 7 modules based on Chirped Pulse Amplification (CPA) and multistage amplifiers, FEMTOFLASH boasts a sleek industrial design consisting of just 3 modules: an oscillator, an acousto-optic modulator (AOM) and an amplification stage.
At the heart of FEMTOFLASH is our patent-pending laser architecture, based on a unique soliton mode-locked seed oscillator that emits a train of femtosecond pulses at 0.8 GHz repetition rate with the impressive average power of 5 W.
Harnessing the remarkable performance of the oscillator, only one high-gain single-stage amplifier is all that’s needed to achieve an average output power exceeding 50 Watts.
This streamlined design eliminates CPA and fiber pre-amplifier stages and reduces number of laser components for a more compact and rugged USP laser.
FEMTOFLASH is a GHz bursts ultrashort pulse laser suited for industrial micromachining.
