The IPLS is a safe and effective modality to treat leg veins ranging in size from 0.1 to 3 mm in diameter.

The method for laser and light assisted hair removal is based on the theory of selective photothermolysis. Selective absorption of hair chromophores from lasers and broad band light sources results in destruction of hair follicles while leaving the skin undamaged. A discussion of the basic principles of selective photothermolysis as it applies to hair removal by lasers and light sources is presented, followed by a comparative review of three melanin target based systems: Ruby laser, Alexandrite laser, and a broad band intense pulsed light. These systems are efficient and safe with proper patient selection. Multiple treatments are necessary due to the nature of the hair growth cycle.

We report the achievement of buried single-mode waveguides in special Boro-Aluminum-Silicate glass. The waveguides are characterized by very low propagation loss (< 0.1dB/cm) and negligible birefringence. The optical mode at the input and output ports is essentially identical to the mode of a standard single-mode optical fiber. We fabricated and tested several devices and report here 1x8 and 1x16 powers splitters and an interleaver defined for a 100GHz DWDM network.Due to the low birefringence of the waveguides, the TE and TM responses of the device are undistinguishable by customary characterization equipment. In addition we report a technique for permanent trimming of the optical circuit by localized heating. This unique advantage of ion-exchange technology, allowed us the adjustment of devices' parameters at post-fabrication stage. As an example, the trimming of a 2x2 directional coupler manifested here in the control of coupling coefficient value over a wide range (0.04-1 .5). The process control was such that a target value of 0.5 for the coefficient was accurately attained. The same process enabled us the tuning of the interleaver to the ITU grid within 1 Opm accuracy.

A cloud of (5 to 10 keV) electrons is injected into a magnetic mirror field. The magnetic field rises in 40--120 µ,sec to a maximum of 10 kG. Two methods of injection were tried: In the first, the injector is located at the mirror midplane and electrons are injected perpendicular to the magnetic field lines. In the second scheme, the injector is located near the mirror maximum. Up to about 10 11 electrons were trapped in both schemes with a mean kinetic energy of 0.3 MeV. Measured confinement time is limited only by the magnetic field decay time. The compressed electron cloud executes electrostatic oscillations. The frequency of the oscillation is proportional to the number of electrons trapped, and it is independent of the value of the magnetic field and the initial electron energy. The electron cloud was ejected along the mirror axis and properties of the ejected electron cloud were measured by x-ray pulses from bremsstrahlung o f electro ns on the vacuum system wall a nd by collecting t:lec tro ns o n a Faraday cup .
