Which laser is tunable?
Among the types of tunable lasers are excimer lasers, gas lasers (such as CO2 and He-Ne lasers), dye lasers (liquid and solid state), transition metal solid-state lasers, semiconductor crystal and diode lasers, and free electron lasers.
What is a tuning range?
[′tün·iŋ ‚rānj] (electronics) The frequency range over which a receiver or other piece of equipment can be adjusted by means of a tuning control.
What is Fabry Perot laser diode?
A Fabry–Pérot laser diode (FP laser diode) is the most common type of laser diode, having a laser resonator which is a Fabry–Pérot interferometer. This means that substantial light reflections occur at both ends, but not within the gain medium.
What are the applications of tunable lasers?
Applications of Tunable Lasers. Wavelength-tunable laser sources have many applications, some examples of which are: In spectroscopy, a wavelength-tunable laser with narrow optical bandwidth can be used for recording transmission or absorption spectra with very high frequency resolution.
What is the tunable range of a laser?
Dye lasers and some vibronic solid-state lasers have extremely large bandwidths, allowing tuning over a range of tens to hundreds of nanometres. Titanium-doped sapphire is the most common tunable solid-state laser, capable of laser operation from 670 nm to 1,100 nm wavelength.
Which tunable lasers are available from Rp photonics?
The RP Photonics Buyer’s Guide contains 92 suppliers for tunable lasers. Among them: HÜBNER Photonics offer tunable lasers from 450 nm up to the MIR based on OPO technology in the Cobolt Odin Series and C-WAVE.
When was the first tunable laser invented?
Tunable source can be a powerful tool for reflection and transmission spectroscopy, photobiology, detector calibration, hyperspectral imaging and steady-state pump probe experiment to name only a few. The first true broadly tunable laser was the dye laser in 1966. Hänsch introduced the first narrow-linewidth tunable laser in 1972.
