Title: David W Watt: Innovator in Lasing Gas Technologies

Introduction

David W Watt is a notable inventor based in Exeter, NH (US). He has made significant contributions to the field of lasing gas technologies, holding a total of 2 patents. His work focuses on improving the efficiency and effectiveness of alkali vapor laser systems.

Latest Patents

Watt's latest patents include innovative techniques and apparatus for managing lasing gas concentrations. These techniques are designed to control and stabilize the concentration of alkali vapor in a lasing gas volume, ensuring it remains at a desired fraction of its saturation value. This is particularly important under dynamically changing thermal loads, as it helps prevent condensation of the alkali vapor during the operation of alkali vapor laser systems, such as diode-pumped alkali laser (DPAL) systems.

Another significant patent by Watt involves optical surface preservation techniques and apparatus. This invention aims to protect optical surfaces in flowing gas amplifier laser systems from chemical attacks and fouling. By matching the geometry of the pumping volume with that of the lasing volume, Watt's techniques minimize the effects of amplified spontaneous emission (ASE) on DPAL output power, enabling systems to produce beam output power ranging from about 20 kW to 10 MW or greater.
