nce solely a research tool, the laser is now an enabling technology for a wide range of applications in semiconductor manufacturing and inspection, industrial marking, materials processing, biomedical systems, reprographics, information display, and telecommunications. Given today’s accelerated product-development schedules, laser-based optical systems are being pushed to produce finer resoluti...

The use of high-power diode laser with a wavelength of 755 nm is an effective and safe method for the correction and partial and/or total elimination of pigmented lesions, specifically solar lentigines. This wavelength has yet not been used in diode lasers to treat solar lentigines. Side effects are the usual ones, including darkening and scab formation. Our patient was a 40-year-old woman of C...

OVERVIEW Mirrorcle Technologies Gimbal-less Two-Axis Scanning MEMS Mirror Devices are based on proprietary ARI-MEMS fabrication technology initially developed through research projects at the Adriatic Research Institute (“ARI”) in Berkeley, CA. They provide very fast optical beam steering across two axes, while requiring ultra-low power. The mirrors deflect laser beams or images to optical scan...

Lymphoedema and Laser Therapy Clinic, Adelaide, South Australia and a current director of the Australasian Lymphology Association Laser is amplified electromagnetic radiation in a particular wavelength range (measured in nanometres [nm]) produced by electronically stimulating a medium to release photon bundles of energy. Medical lasers can be broadly generalised into: 8 High output lasers that ...

We report on a femtosecond nonlinear amplification fiber laser system using a vector-dispersion compressor, which consists of a transmission grating pair and multipass cell based Gires-Tournois interferometer mirrors. The mirror is designed with nearly zero group-delay dispersion and large negative third-order dispersion. As a result, the third-order dispersion of the compressor can be adjusted...

We report on the development of high actuator count, micro-electromechanical (MEMS) deformable mirrors designed for high order wavefront correction in ground and space-based astronomical adaptive optics instruments. The design of these polysilicon, surface-micromachined MEMS deformable mirrors builds on technology that has been used extensively to correct for ocular aberrations in retinal imagi...

This paper reports on a novel approach for producing high energy femtosecond pulses without external amplification. The so-called chirped-pulse oscillator ~CPO! concept is based on an extended-cavity oscillator, operating at small net positive intracavity group delay dispersion ~GDD!, over a broad spectral range by the use of chirped multilayer mirrors. The resultant chirped picosecond pulses a...

In this paper, we present a high accuracy laser range finder and velocimeter using ultra-fast time-to-digital converter (TDC). The system operation is based on the measuring the round-trip time of a narrow laser pulse. A low-dark current high-speed PIN photodiode is used to detect the triggered laser beam and to produce start signal. The pulsed laser diode generates 45W optical power at 30ns du...

In the following work a manufacturing process for light weight structures in Fused Silica is presented. Such can potentially be used mirrors to decrease mass by simultaneously ensuring high stiffness. This talk should give audience possibility assess selective laser etching technology mechanical field of optical mirrors.

This report outlines the possibilities to be found using one or more diffraction-limited high-quality light beams to activate a weakly absorbing gas in a regime where the diffraction spread can be controlled by converging optical devices to within a ratio ofJ2 of the minimum at the beam waist (corresponding lengths between converging elements are within twice the Rayleigh range). Our desigr.s u...
