Question

Statement 1 : Diode lasers are used as optical sources in
optical communication.
Statement 2 : Diode lasers consume less energy.

Answer 1

Answer:

Optical cavity and laser modes

As in other lasers, the gain region is surrounded with an optical cavity to form a laser. In the simplest form of laser diode, an optical waveguide is made on that crystal's surface, such that the light is confined to a relatively narrow line.

Diode lasers use much less power than most types of lasers. While gas and solid-state lasers require a power supply in kilo-volts, diode lasers typically run on small volt batteries.

Answer 2

Answer:

so sorry I didn't get answer Diode
