Abstract

A laser configured to optimise output power at a desired wavelength, by suppression of unwanted Stokes orders in a Raman cascade, the laser comprising a resonating structure configured to resonate precursor light and Raman light frequencies, having a Raman medium configured to interact with the precursor resonating light to generate the Raman light; a control nonlinear medium configured to reduce an extraction of power from the precursor resonating light by the Raman process; and an output nonlinear medium configured to interact with the precursor resonating light to generate a desired output light thereby extracting power from the precursor resonating light; whereby the control nonlinear medium reduces the extraction of power from the precursor resonating light by the Raman process to enhance the extraction of power from the precursor resonating light by the output nonlinear medium interacting with the precursor resonating light thereby increasing the power of desired output the light.
