Although the feasibility of using femtosecond laser pulses for a broad range of machining applications has been known for a decade, the technology's widespread implementation in industry has been hindered by the lack of suitable light sources.
FemtoLasers Produktions GmbH of Vienna, Austria, has designed a technique that enables the generation of high-energy femtosecond pulses directly from an oscillator with no need for amplification. The Femtosource Scientific XL chirped pulse Ti:sapphire oscillator enables micro- and nanomachining with a megahertz pulse train at nearly full average power.
The compact system, measuring 900 × 450 mm, incorporates a pump laser with a patented resonator configuration and an active feedback loop for stable, longtime laser operation. Generating 40-fs, 100-nJ pulses with a repetition rate of 11 MHz and a bandwidth of >50 nm, it can be used with virtually any type of material and for applications ranging from drilling holes in stainless steel injection nozzles to fabricating photonic crystals or waveguides. Other potential uses are time-resolved spectroscopy, two-photon microscopy and amplifier seeding.
