Markettechinc is an online source for tunable lasers. Another reputable company is Santec. This company also has an online presence where the tunable lasers are sold.
Tunable laser diodes measure the concentration of gases in an area. The advantages of tunable laser diodes is that they are able to detect very low levels of these gases.
Tunable lasers are commonly used for recording transmission data, or absorption information. In some applications, cooling is required, and tunable lasers are good for that use as well.
All tunable LASERs are LASERS, however not all LASERS are tunable. In a tunable laser the lasing medium, which is typically a gas, dye or crystal, can be altered to produce slightly different frequencies, thus allowing the laser to be 'tuned' or frequency changed where most LASERS produce a very narrow band of radiation frequencies.

UV lasers are good for analyizing top surface layers. It has a penetration depth of only a few nanometers, making it incredibly sensitive, even to very thin layers.
Tunable lasers can be tuned in various manners. Some of these include single line and multi line tuning. Narrow band tuning is also used to tune various lasers as well.
he was co-inventor the 'spin-flip tunable laser'.
The common features in a wireless stereo transmitter are 1689 tunable UHF frequencies for interference-free reception, an enhanced frequency bank system with 12 tunable frequencies, and an enhanced AF frequency range.
If they are tunable, yes you can. If the operating frequency is locked, no, you cannot.
