DEVICE, SYSTEM AND METHOD FOR PRODUCING A SINGLE LONGITUDINAL MODE LASER OUTPUT - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240055821 titled 'DEVICE, SYSTEM AND METHOD FOR PRODUCING A SINGLE LONGITUDINAL MODE LASER OUTPUT

Simplified Explanation

The patent application describes a Raman laser conversion device that generates a single longitudinal mode (SLM) laser output by utilizing a Raman medium that exhibits Stokes emission when pumped by a laser input.

  • The device includes a Raman medium that defines feedback interfaces of a resonator to resonate the Stokes emission within the medium.
  • The free spectral range (FSR) of the resonator is designed in such a way that only one longitudinal mode of the Stokes emission can resonate within the Raman medium.
  • This results in the generation of a SLM laser output that is frequency shifted with respect to the laser pump input.
    • Potential Applications:**
  • Telecommunications
  • Spectroscopy
  • Laser material processing
  • Medical applications
    • Problems Solved:**
  • Generation of a SLM laser output
  • Frequency shifting of laser output
  • Enhancing laser performance and precision
    • Benefits:**
  • Improved laser output quality
  • Enhanced precision in applications such as spectroscopy and medical procedures
  • Increased efficiency in laser material processing.


Original Abstract Submitted

a raman laser conversion device for generating a single longitudinal mode, slm, laser output is disclosed. the device comprises a raman medium that exhibits a stokes emission when subject to pumping by a laser pump input, the laser pump input having a pump linewidth and the raman medium having a raman linewidth; wherein the raman medium is configured to define feedback interfaces of a resonator such that the stokes emission resonates within the raman medium; and further wherein the free spectral range, fsr, of the resonator with respect to the pump linewidth and/or the raman linewidth or a function thereof is such that only one longitudinal mode of the stokes emission is able to resonate within the raman medium; whereby the laser conversion device generates a slm laser output that is frequency shifted with respect to the laser pump input.
