Title: The Innovations of David James Spence

Introduction

David James Spence is a notable inventor based in Forestville, Australia. He has made significant contributions to the field of laser technology, holding a total of five patents. His work focuses on advanced laser systems and electromagnetic radiation generation.

Latest Patents

One of his latest patents is the "Single Longitudinal Mode Ring Raman Laser." This invention includes a pump source that outputs a pump light power, which is resonantly coupled to a first ring resonator. The system features an optical measurement and piezo-actuator for stabilizing the resonant coupling of the pump light power to the first ring resonator. The first ring resonator contains a Raman gain medium that receives the pump light power and undergoes Raman lasing, generating resonated Stokes power at the corresponding Stokes output wavelength. This resonator acts as a feedback loop for both the pump light power and the resonated Stokes power, outputting a portion of the Stokes power as the laser output.

Another significant patent is related to "Terahertz Lasers and Terahertz Extraction." This invention describes a frequency electromagnetic radiation generation system that includes a non-linear crystal producing THz frequency electromagnetic radiation. A fundamental beam interacts with the non-linear crystal, emitting THz frequency electromagnetic radiation. The system utilizes a silicon intermediary coupled to the non-linear crystal for output channeling the THz frequency electromagnetic radiation emission to an output environment. Notably, the fundamental beam has a photon energy below the bandgap energy of silicon.
