Abstract
Official abstract text for this publication.
A system, method and apparatus for operating a laser at a downhole location is disclosed. A gas is configured to receive an output of a laser and to absorb a selected wavelength of the laser corresponding to a selected spectral line of the gas. A pressure device reduces broadening of the selected spectral line related to a temperature at the downhole location. A photodetector receives light from the gas chamber and provides a measurement related to the received light. A processor alters an operating parameter of the laser using the obtained measurement to operate the laser.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of operating a laser at a downhole location, comprising: directing a laser beam from the laser onto a gas disposed at the downhole location; reducing a broadening of a selected rotational-vibrational absorption line of the gas related to a temperature at the downhole location; obtaining a measurement related to absorption of the laser at the selected rotational-vibrational absorption line; and altering an operating parameter of the laser usin…
