Laser Diodes, Laser Modules

1. Overview

Laser diodes (LDs) are semiconductor devices that emit coherent light through stimulated emission. Laser modules integrate LDs with optical components, drivers, and thermal management systems. These devices are critical in telecommunications, medical systems, industrial processing, and consumer electronics due to their high efficiency, compact size, and precise beam control.

2. Main Types and Functional Classification

TypeFunctional FeaturesApplication Examples
Edge-Emitting Laser DiodesHigh power output, narrow spectral widthFiber optic communication, LIDAR
Vertical-Cavity Surface-Emitting Lasers (VCSELs)Low divergence beam, array scalability3D sensing, data centers
Quantum Cascade LasersTunable mid-infrared emissionGas sensing, spectroscopy
Fiber-Coupled Laser ModulesIntegrated beam shaping, wavelength stabilizationMaterial processing, medical surgery
Multi-Transverse Mode LasersHigh brightness, multimode outputLaser projection, defense systems

3. Structure and Components

Laser Diodes: Composed of an active region (quantum well structure), cladding layers, and a resonant cavity formed by cleaved facets. Electrical contacts enable current injection.

Laser Modules: Integrate LDs with:

  • Collimating optics and beam-shaping elements
  • Photodiode feedback for power stabilization
  • Thermoelectric coolers (TEC) for temperature control
  • Driver circuits with modulation capabilities

4. Key Technical Specifications
