    Current trends of intelligent products and controlled processes show an increasing need for long-living sensors. Metal thin-film strain gauges are suitable for monitoring mechanical loads over the entire lifetime of a component. However, existing manufacturing methods can only pattern these gauges on flat components and in large quantities...

    Passive mode-locked pulse lasers applying erbium-doped fiber have about 100 fs pulsewidth that is near the Fourier-limited pulse. However, femtosecond pulses are often demanded for more longer pulsewidth, because high energy pulses are useful in processing. In this study we develop a continuously variable pulsewidth laser using novel method applying coherent coupling,...

    Presented at ICALEO 2013

    The main purpose of this work was to study the surface topography of bovine femoral bone treated with a femtosecond infrared laser and the changes in the bone structure and composition induced by laser ablation. The laser treatments were carried out using a Yb:KYW chirped-pulse-regenerative amplification laser with a pulse duration of about 500 fs, a wavelength of 1030 nm and fluences ranging from 0.55 to 1.09 J/cm2. The ablation process was monitored in real time by acoustic emis...
