We presented a tunable optofluidic dye laser with integrated elastomeric air-gap etalon controlled by air pressure. The chip was fabricated with polydimethylsiloxane (PDMS) via replica molding. It comprises a liquid waveguide and microscale air-gap mirrors ...
Stereo reconstruction is a fundamental problem of computer vision. It has been studied for more than three decades and significant progress has been made in recent years as evidenced by the quality of the models now being produced. This is highly related w ...
We present our evaluation of a compact laser system made of a 795 nm VCSEL locked to the Rubidium absorption line of a micro-fabricated absorption cell. The spectrum of the VCSEL was characterised, including its RIN, FM noise andline-width. We optimised th ...
The intervertebral disc (IVD), which provides flexibility to the spine and facilitates damping and motion, is composed of two distinct structures: the annulus fibrosus (AF) and the nucleus pulposus (NP). The AF, which is fibrous and elastic, confines the N ...
A 1.6 mu m mode-locked Raman fiber laser pumped by a 1480 nm semiconductor disk laser is demonstrated. Watt-level core pumping of the single-mode fiber Raman lasers with low-noise disk lasers together with semiconductor saturable absorber mirror mode locki ...
We report the first (to our knowledge) wafer-fused high-power passively mode-locked semiconductor disk laser operating at 1.57 mu m wavelength. An InP-based active medium was fused with GaAs/AlGaAs distributed Bragg reflector on a 2 inch wafer level, resul ...
In this work we demonstrate an integrated air-gap etalon that enables single wavelength operation and tuning ability for optofluidic dye laser. The integrated elastomeric air-gap etalon is controlled by air pressure. The chip was fabricated with polydimeth ...
We report quantitative dissociation yields for the reaction CH3OH (v(OH))-->nhnu CH3+OH induced by infrared multiphoton excitation of methanol pre-excited to various levels of the OH stretching vibration (v(OH)=0, 1, 3, 5). The yields are measured by detec ...
High resolution magnetic force microscopy plays an important role in the development of magnetic data storage media. Particularly the envisioned increase of the storage density to 1TBit per sqinch within the next five years requires an ongoing development ...
A new procedure for laser spot welding of thin copper stripes was developed based on measuring the calibrated reflectivity coaxially to the laser beam and using this signal for in situ control of the laser power. Experiments with a power ramp of r=3.1 MW/s ...
