hi , does input light signal for laser amplification has to be provided by the external source or it is created by lasing material itself?
The input light signal for a laser is the energy source that is used to stimulate the atoms or molecules in the laser's gain medium, causing them to emit photons and produce a coherent laser beam.
Various types of light can be used as the input signal for a laser, including visible light, infrared light, ultraviolet light, and even X-rays. The specific type of light used depends on the type of laser and its intended application.
The input light signal is typically delivered to the laser through an optical fiber or through mirrors and lenses. This allows the light to be directed and focused onto the laser's gain medium.
Yes, the input light signal can affect the output of a laser. The characteristics of the input signal, such as its intensity, wavelength, and polarization, can impact the properties of the resulting laser beam.
The input light signal can be controlled in a laser system through various methods, such as adjusting the power of the light source, changing the angle or position of the mirrors and lenses, or using filters to modify the wavelength or polarization of the light.
