Title: The Innovations of Charles E. Wiswall

Introduction

Charles E. Wiswall is a notable inventor based in Hazelwood, MO (US). He has made significant contributions to the field of technology, holding a total of 3 patents. His work primarily focuses on advancements in laser technology and absorption cells.

Latest Patents

One of Wiswall's latest patents is the Long Path Absorption Cell. This invention features a small volume long path absorption cell of the White-type, designed for use with condensable samples. The absorption cell is temperature controlled and can operate over a temperature range of -10 degrees C to 80 degrees C. To prevent condensation on the mirror surfaces, the mirrors are individually temperature controlled and maintained a few degrees above the ambient temperature of the absorption cell. The mirrors are mounted on an Invar framework, which minimizes variations in path length due to thermal expansion. The cell's temperature is regulated by a jacket containing a heating or cooling fluid, and the controls for the mirrors are adjustable from the exterior, allowing operation at both above and below atmospheric pressure.

Another significant invention is the High-Power CO Laser. This application discloses a laser that operates independently of oxygen atom dissociators and does not require any electrical input, making it a purely chemical CO laser. The combustion is fueled by a suitable fuel-oxidizer mixture, such as CH₄–H₂–CS₂–NF₃, which dissociates CS₂ into CS and S. The S atoms generated in the combustor initiate a chain reaction where S, O₂, and CS react, converting all CS into excited CO that lases in the optical cavity.
