We report on the world’s first experiment of a parallel profile scan of the hydrogen ion (H) beam using a laser wire system. The system was developed at the superconducting linac (SCL) of the Spallation Neutron Source (SNS) accelerator complex. The laser wire profile scanner is based on a photo-detachment process and therefore can be conducted on an operational H beam in a nonintrusive manner. ...

The Multiple Mirror Telescope (MMT) will be converted to a single-mirror telescope in early 1998. Adaptive optics using a sodium laser guide star will be an integral part of the new telescope with adaptive correction made at the secondary mirror. The MMT AO system is under development, and will be completed for sky tests soon after telescope first light. In this paper, we give an overview of th...

The double chirped mirror DCM appeared to meet the need to compensate for the gain crystal dispersion of solid state lasers in a broad wavelength range. Compared to earlier dispersion compensation techniques, they enabled remarkable improvements in the field of generating ultra short pulses. When ultra broad band gain media are used inside laser cavities, cavity dispersion plays an important ro...

Since the stereolithograpy system appeared on the market, various rapid prototyping machines based on the layer laminated manufacturing process have emerged one after the other, the range of applications of which is classified according to their features. Of these, stereolithogrraphy methods which make use ofphotocurable resin as material and laser beam as processing tools are gradually being e...

The advent of ultrahigh-power femtosecond lasers creates a need for an entirely new class of optical components based on plasmas. The most promising of these are known as plasma mirrors, formed when an intense femtosecond laser ionizes a solid surface. These mirrors specularly reflect the main part of a laser pulse and can be used as active optical elements to manipulate its temporal and spatia...

We have developed a fast multi-wavelengths switching laser platform. The tuning mechanism is based on a micro-mirror array DLP chip from a commercial pico-projector forming the end mirror of an external cavity laser diode. We report progress on a working prototype of a single frequency laser with a wavelength that is switchable between any five wavelengths spanning 765 nm to 783 nm. Switching t...

We propose a technique aimed at cooling a harmonically oscillating mirror to its quantum mechanical ground state starting from room temperature. Our method, which involves the two-sided irradiation of the vibrating mirror inside an optical cavity, combines several advantages over the two-mirror arrangements being used currently. For comparable parameters the three-mirror configuration provides ...
