Injection locking has also been used in high performance frequency doubling circuits.
2.
Instead frequency doubling can be used to provide the green wavelengths.
3.
Every time the pitch goes up one octave, the frequency doubles.
4.
Practically, frequency doubling is carried out by placing a nonlinear medium in a laser beam.
5.
This then, SHG producing crystals have been used to frequency double lasers to obtain shorter wavelengths.
6.
The frequency doubling illusion can also be used to detect glaucoma with the use of a frequency doubling technology perimeter.
7.
The frequency doubling illusion can also be used to detect glaucoma with the use of a frequency doubling technology perimeter.
8.
Applications for electrically pumped VECSELs include projection displays, served by frequency doubling of near-IR VECSEL emitters to produce blue and green light.
9.
Second-harmonic light emerging from a SHG material is exactly half the wavelength ( frequency doubled ) of the light entering the material.
10.
There was a strong program in inorganic non-linear optical materials that resulted in optical frequency doubling for the green lasers mentioned above.
