Low wavelength infrared Super Continuum (SC) signals from a master oscillator seeds an amplifier that supports the Raman effect. Counter-propagating, high-power, continuous wave, and quasi-continuous wave quantum cascade lasers pumps (amplify) the optical seeds forming multiple coherent wavelength optical pump sources.

Multiple coherent wavelength optical sources

A resonating optical amplifier includes a laser pump cavity defined by a first mirror and a second mirror with a laser pump gain medium configured within a first portion of the laser pump cavity and a Raman amplifier within a second portion of the laser pump cavity. A circulating pump-laser light is introduced to the laser pump gain medium forming a pump signal that is configured to bi-directionally propagate along a beam path within the laser pump cavity. The Raman amplifier is positioned in line with the beam path of the pump signal and operable to impart gain on a seed pulse. The seed pulse and the pump signal are co-aligned and linearly polarized.

Raman amplifier with shared resonator

A high brightness, wavelength-adjustable, deep-UV-C light source identifies, neutralizes, and validates the absence of one or more pathogens. An optical source using a Raman-based nonlinear optical amplification process converts low brightness continuous wave (CW) and Quasi-CW pump light into high brightness and high peak power optical UV-C radiation at a specific wavelength, pulse duration, repetition rate, and optical bandwidth for targeted pathogen identification, neutralization, and absence validation. A tunable Raman-based output operates at a wavelength between 400 nm and 460 nm, which is employed for Raman spectroscopic pathogen detection, and which is frequency doubled to the Deep-UV-C (DUV-C) spectral region of between 200 nm to 230 nm for fluorescence detection of potential pathogens.
