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.

What are the example of liquid laser?
Some examples of liquid lasers are dye lasers, which use organic dyes dissolved in a solvent as the gain medium, and liquid crystal lasers, which use liquid crystal materials to create the gain necessary for laser emission. These liquid lasers have tunable emission wavelengths and can be used in various research and industrial applications.
What is the difference between cold and hot lasers?
Cold lasers are safer and deal less pain than hot lasers. Cold lasers are usually used for repairing skin damage and treating pain and inflammation. Hot lasers are simply used for burning things.
What is the spin flip tunable laser?
The spin-flip tunable laser employs the Raman effect to change the emitted frequency of light. They normally operate in the microwave or infrared sections of the electromagnetic spectrum. We (as humans) can only see the visible light section of the electromagnetic spectrum, and both sections the lasers operate in are outside of that range.This is the simplified answer. If you want a more scientific explanation of how it works, see . It's not at the top, you have to scroll down to "Description of the Background of Spin-Flip Raman Lasers" under the second image.Source:https://webfiles.uci.edu/mcbrown/display/shaw.html
What is grating in laser?
Grating in laser refers to a diffraction grating, which is a device that uses interference to disperse light into its component colors. It is often used in lasers to select specific wavelengths of light or to create tunable laser systems by changing the angle of the grating.
What is the difference between the continuous laser and pulsed laser?
Continuous lasers emit a continuous beam of light, while pulsed lasers emit light in short bursts or pulses. Continuous lasers are used for applications requiring steady illumination, while pulsed lasers are used for applications requiring high peak power in a short duration.
What are some tunable laser sources?
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.
What is a tunable laser used for?
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.
What are the different types of tuning in tunable laser?
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.
What are the example of liquid laser?
Some examples of liquid lasers are dye lasers, which use organic dyes dissolved in a solvent as the gain medium, and liquid crystal lasers, which use liquid crystal materials to create the gain necessary for laser emission. These liquid lasers have tunable emission wavelengths and can be used in various research and industrial applications.

What is the difference between lasers?
well some lasers can burn and some cannot. and some that cannot are more powerful than others
What are the advantages of tunable laser diodes?
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.
What are the differences between a free-electron laser and a conventional laser?
Free-electron lasers were invented at Stanford University by John Madey. While these lasers share the same optical properties as conventional lasers, the main difference between the two is the principal they use to form the beam.
