About Diode Lasers

The word laser is an acronym for “Light Amplification by Stimulated Emission of Radiation”, which means a device that produces and amplifies light. Lasers require a power supply and an active medium in order to produce light. Diode Lasers feature a semiconductor crystal as the active medium that is “pumped” when an electrical current is passed through it, causing the release of photons which produces coherent, monochromatic light. The light is then collimated (focused), and directed into a fiber optic which carries it to the target tissue.  When the light enters the tissue, the energy is converted into heat.

Compared to surgical scalpels, diode lasers are less invasive and more precise. They provide disinfection of the surgical area, less discomfort during treatment, less inflammatory response, and less post-surgical pain. A laser cuts the tissue and cauterizes the wound, providing immediate hemostasis.

The 810nm wavelength

One of the most important features of a laser is its wavelength, as this determines the types of tissues that will be affected by the laser energy, and therefore what procedures the laser can perform. The near-infrared 810nm wavelength was specifically selected for Pioneer Elite and Pioneer Pro Soft Tissue Diode Lasers because the 810nm wavelength achieves a good balance of absorption by hemoglobin and melanin chromophores, which are prevalent in oral soft tissue and water. When these substances in the tissue absorb the specific wavelength, the tissue is vaporized and immediate cauterization results. The 810nm is ideal for vascularized tissue, it is minimally invasive, and it offers superior coagulation and rapid healing.

Pulsed and continuous wave modes

Laser light can be emitted in either pulsed or continuous wave mode. The Pioneer Elite and Pioneer Pro lasers are designed to deliver both. In continuous mode, beam power intensity remains constant over time and the laser energy is delivered in a continuous, uninterrupted manner, the laser is faster and more efficient, but more heat is generated and transferred within the tissue.  In pulse mode, laser radiation is emitted intermittently as consistent short bursts or pulses of energy. Pulse mode is less aggressive and allows tissue cooling between pulses.  When the Pro and Elite diode lasers are used in continuous mode, the average power will be what is selected on the control panel.  In pulse mode, the average power will be half of the set power, since the laser is only emitting energy half of the time. 

An 810nm diode laser offers a dental professional great versatility in the treatments for which it can be used.
