Title: Innovations of Leo H Szeto

Introduction

Leo H Szeto is a notable inventor based in Howell, NJ (US). He has made significant contributions to the field of plasma technology, holding a total of 5 patents. His work primarily focuses on advancements in laser technology and plasma excitation.

Latest Patents

One of Szeto's latest patents is the Segmented Plasma Excitation-Recombination Light Source. This invention involves applying an electrical signal, such as a high current pulse, to a series of conducting strips installed in a laser cavity. The strips are separated by small gaps, and when the electrical signal is applied, plasmas are formed in these gap regions. The plasmas consist of ions from the strip material and expand hemispherically, cooling and recombining to generate radiation. The composition of the plasmas is influenced by various factors, including the strip material and the background gas type and pressure.

Another significant patent is the External Control of Recombination Rate for Electron-Ion Recombination. This invention comprises an apparatus that provides a combination of excitation pulses to a plasma-recombination laser. It creates the plasma and controls the electron-ion collisional recombination rate. The application of a single shaped excitation pulse or a combination of pulses maintains the electron temperature of the plasma at a level unfavorable to recombination until the electron density reaches the optimal range for laser action. The termination of the excitation pulse results in immediate laser action with power significantly greater than that achieved in prior art.
