Abstract
Generating broadband light downhole for wellbore application. A laser source is configured to reside outside a wellbore and produce a seed light pulse at a first wavelength spectrum. A converter is configured to be received inside the wellbore, remote from the laser source. The converter receives the seed light pulse at the first wavelength spectrum through one or more fiber optic cables, and generates light at a second wavelength spectrum that has a broader range than the first wavelength spectrum.
Claims20
A system for producing broadband light in a wellbore, the system comprising:
- a laser source that produces a seed light pulse at a first wavelength spectrum;
- and
- a converter configured to be received in a wellbore, the laser source adapted to reside remote from the converter, the converter to receive the seed light pulse at the first wavelength spectrum and generate light at a second wavelength spectrum that has a broader range than the first wavelength spectrum.
A method for producing broadband light in a wellbore, the method comprising:
- generating a seed light pulse at a first wavelength spectrum outside a wellbore;
- transmitting the seed light pulse at the first wavelength spectrum to a downhole location inside the wellbore;
- and
- at the downhole location, converting the seed light pulse at the first wavelength spectrum into light at a second wavelength spectrum that has a broader range than the first wavelength spectrum.
A system for producing broadband light in a wellbore, the system comprising:
- a laser pulse generator adapted to reside at a surface outside a wellbore that produces a seed light pulse at a first wavelength spectrum, the seed light pulse having a first power;
- a laser source to generate a light at a third wavelength spectrum of lesser wavelength than the first wavelength spectrum;
- a downhole amplifier to amplify the seed light pulse into a pulse at the first wavelength spectrum, the pulse having a second power that is greater than the first power;
- and
- a downhole converter adapted to reside downhole inside the wellbore, the downhole converter to broaden the pulse having the second power into light at a second wavelength that has a broader range than the pulse at the first wavelength spectrum.
