Laser Diodes Vs LEDs

Laser Diodes Vs LEDs – The Facts

A great deal has been written over time regarding the debate between laser diodes and LEDs and as to which is superior for use in therapeutic applications. The following is a summary covering the scientific facts concerning laser diodes and LEDs.

Laser diodes and LEDs (Light Emitting Diodes) are both used in cold laser therapy, also known as low-level laser therapy (LLLT). Here’s a breakdown of the differences between laser diodes and LEDs in this context:

1. Wavelength:

  • Laser Diodes: Emit a coherent (single wavelength) and monochromatic (single color) light. This allows for precise targeting of specific tissues and depths.
  • LEDs: Emit non-coherent and polychromatic (multiple wavelengths/colors) light. They cover a broader area but lack the coherence of laser diodes.

2. Power Density:

  • Laser Diodes: Typically have higher power densities compared to LEDs, which can penetrate deeper into tissues due to their focused beam.
  • LEDs: Have lower power densities and are better suited for superficial treatments or broader coverage.

3. Treatment Depth and Targeting:

  • Laser Diodes: Penetrate deeper into tissues, making them suitable for targeting specific points or deeper injuries.
  • LEDs: Are effective for surface-level treatments or covering larger areas of the body.

4. Clinical Applications:

  • Laser Diodes: Commonly used for precise treatments such as acupuncture points, trigger points, and deep tissue injuries.
  • LEDs: Used for more general applications like wound healing, reducing inflammation, and pain management over larger areas.

5. Cost and Practicality:

  • Laser Diodes: Typically more expensive due to their coherent nature and higher power capabilities.
  • LEDs: Generally more cost-effective and easier to use over large areas due to their broader coverage.
