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.
| Type | Functional Features | Application Examples |
|---|---|---|
| Edge-Emitting Laser Diodes | High power output, narrow spectral width | Fiber optic communication, LIDAR |
| Vertical-Cavity Surface-Emitting Lasers (VCSELs) | Low divergence beam, array scalability | 3D sensing, data centers |
| Quantum Cascade Lasers | Tunable mid-infrared emission | Gas sensing, spectroscopy |
| Fiber-Coupled Laser Modules | Integrated beam shaping, wavelength stabilization | Material processing, medical surgery |
| Multi-Transverse Mode Lasers | High brightness, multimode output | Laser projection, defense systems |
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:
