A tunable laser is a laser whose wavelength of process can be changed in a prohibited method. There are many different types of tunable lasers are available like excimer lasers, dye lasers, solid state lasers, diode lasers and free electron lasers. To understand tunable lasers we must put together the information support of various regulations in physics and mathematics.
Tunable lasers are different from the traditional lasers because tunable lasers can endlessly change their production wavelength in a known spectral range. We utilize the tunable lasers in many fields like communications, imaging, interferometry, materials processing, medicine, microscopy, remote sensing and ranging. Tunable lasers are also played a vital and continued position in development of fundamental physics and science.
