A Fabry-Perot laser diode is an oscillator in which two mirrors are separated by an amplifying medium with an inverted population, making a Fabry-Perot cavity. Standard diode lasers are Fabry-Perot lasers.
Fabry-Perot laser diodes are the most common type of diode laser and are the most economical, but they are generally slower and more noisy than distributed feedback (DFB) lasers.
