Are diode lasers tunable?
Tunable, single-frequency lasers not only for quantum technologies. Tunable single-frequency diode lasers utilize a laser diode and a frequency selective element like a grating for laser frequency selection and tuning.
What is tunable diode laser analyzer?
Tunable diode laser analyzers (TDL analyzers) are gas analyzers designed for measuring the concentration of specific species within a gas mixture using laser absorption spectrometry.
What are laser diode arrays used for?
High-power laser-diode arrays, which are made of stacks of individual or multistripe laser diodes, or in some cases vertical-cavity surface-emitting lasers (VCSELs), can put out watts to kilowatts of optical power for uses such as laser pumping, industrial heating, illumination, or as the input for fiber-optic direct- …
How does a tunable diode laser work?
A tunable diode laser emits a wavelength of near-infrared (NIR) light specific for the target analyte into the sample cell where it passes through the gas and is reflected back by a mirror at the opposite end of the cell to a solid state detector.
What is tunable laser source?
A tunable laser is a laser whose wavelength of operation can be altered in a controlled manner. While all laser gain media allow small shifts in output wavelength, only a few types of lasers allow continuous tuning over a significant wavelength range.
How is tunable laser used in fibre optic communications?
This thesis deals with the design, realisation, and testing of the wavelength tunable 1540-nm laser prototypes that are intended for fibre optic communications. The short external cavity laser uses an electrically controlled silicon micromachined Fabry-Perot interferometer (FPI) device as the tuning element.
Which is the best diode laser for mobile use?
Laserline’s diode lasers are long-lasting, low-maintenance, and compactly built for mobile use thanks to their innovative diode cooling technology, and they are even available as a 19″ rack mount laser. Furthermore, customized laser designs are designed, created and thoroughly tested in our own application laboratory.
Can a tunable laser module be electrically modulated?
The laser module can be electrically modulated up to over 600 MHz. The test results show that the FPI-tuned diode lasers can provide a cost-effective solution for optical communication applications. The study also confirms that it is possible to realise the laser- to-SM-fibre coupling using adhesive bonding.
What can laser diode gas sensors be used for?
