Introduction

EEL (Edge-Emitting Laser) is a type of semiconductor laser where the light is emitted from the edge of the structure. This design is intrinsic to their functionality, distinguishing them from other types like VCSELs (Vertical-Cavity Surface-Emitting Lasers). EELs are notable for their high optical output power and efficiency and are integral to various industrial, telecommunications, and consumer applications.

Principle of EEL Lasers

EELs operate by employing a semiconductor diode, which is a p-n junction. Light is produced by the recombination of electron-hole pairs in the active region of the diode, typically constructed from materials like Gallium Arsenide (GaAs) or Indium Phosphide (InP).

EELs utilize a resonant cavity formed by two mirrors on opposite sides of the semiconductor gain medium. This structure results in stimulated emission, amplifying the light significantly. State-of-the-art EELs can achieve optical output powers of up to 10 watts with efficiencies greater than 50%.

Key Parameters

• Wavelength: Commonly ranges from 630 nm to 1650 nm, depending on the material.
• Output Power: Generally between 5 mW to 10 W, suited for both low-power and high-power applications.
• Efficiency: Can exceed 50% with optimized designs.

Applications of EEL Lasers

EEL lasers are employed across various domains due to their high power and efficiency. Common applications include:

• Telecommunications: Used in fiber optic communication systems for data transmission.
• Industrial: Utilized in cutting, engraving, and other precision processes requiring high-power lasers.
• Medical: Applied in dermatology and surgical procedures due to precision and control.
• Consumer Electronics: Incorporated in optical disc drives and laser printers.
