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.

What are the example of liquid laser?
tunable-dye laser
What is the difference between lasers and tunable lasers?
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 IS NMR frequency?
Electro magnetic radiation in the range of 60Mhz to 1000Mhz frequency necessary to cause a nucleus to spin flip ie the resonance frequency.
What type of laser is a thor laser?
Low level laser also referred to as a cold laser.
What is laser micrometer?
laser is
What did earl d shaw invent?
he was co-inventor the 'spin-flip tunable laser'.
What are the advantages of tunable laser?
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.
What are the example of liquid laser?
tunable-dye laser
Why was earl shaw invention important?
After earning his PhD., Dr. Shaw worked 19 years as a Research Scientist for Bell Laboratories in Murray Hill, New Jersey, where he was the co-inventor of the spin-flip Raman tunable laser. He joined Rutgers in 1991 and moved to the Newark campus a new laser technology - the far-infrared free electron - that he developed at Bell Labs. The laser, which is to be operational in 1999, generates short tunable far-infrared light pulses that will permit the analog or pulsed magnetic resonance techniques for the first time in the optical wavelength regime.
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 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.
Can you flip a Tempur Pedic mattress?
No; spin yes, flip no.
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.
