Getting Familiar with The Basics of Cosmetic Laser Technology

The world has witnessed an increase in the understanding of the biophysics behind the interactions of laser and tissue. This has led to better utilization of the technology and the churning out of increasingly efficient and safer models on the clinical side. Physicians and spas can now get access to highly selective cosmetic laser machines for rent or sale from established dealers such as MedLaserUSA. In this brief, we take a look at the basics of medical laser technology to help you get a better understanding.

A Brief History

The name ‘Laser’ is an acronym for Light Amplification by Stimulated Emission of Radiation. The concept of Stimulated Emission is derived from the quantum theory of radiation from Einstein. The first laser employed ruby as a lasing medium that derived its power from intense flashes of high-energy light. It was developed by Theodore H. Maiman in 1960. In the same year, about ten lasers were born which made use of different lasing media such as gaseous, solid, liquid, and semi-conductor.

The Characteristics of Laser

Laser light has various unique characteristics including being bright, monochromatic, coherent, and unidirectional. Let’s take a closer look at these qualities:

  • Cosmetic Laser machines produce a light which is angularly well-centered and very intense. This brightness can be upped through q-switching and pulsing to target treatment areas with peak power in nanoseconds.
  • The waves from a cosmetic laser machine are of the same energy and wavelength. This enables physicians to attain better targeting during cosmetic laser treatments such as laser tattoo or hair removal.
  •  There is a phase agreement or coherency in respect of time and space in as far as how the emitted photons vibrate.
  • The photons emitted also gravitate in uni direction owing to the slow spread of the narrow light beam. The quality of uni-directionality allows physicians to target small spots while sparing surrounding and underlying tissue.

Cosmetic Laser Terminology

There is various terminology associated with laser technology that all in the industry ought to be familiar with. Here is some of the common terminology.


Lasing refers to the process of targeting lesions with the beam of cosmetic laser light.


Wavelength refers to the distance between 2 subsequent light wave peaks and is expressed in nanometers.


Energy refers to the quantum of energy carried by each photon. Typically, a short wavelength features low energy photons while long wavelengths have high energy photons.


Frequency is related to the wavelength. Short wavelength equals high frequency, while long wavelength equals low frequency.


IPL means Intense Pulsed Light. It achieves peak optical power through capacity banks. The power per pulse can reach 20, 000 watts and wavelengths of 400 nm to 1200 nm.


Chromophore refers to endogenous or exogenous material in the tissue. The material is capable of absorbing specific wavelengths according to its absorption coefficient.


Photon refers to the elementary particle behind the electromagnetic phenomenon. It provides a vehicle to all wavelengths of electromagnetic radiation.


While ablative cosmetic laser treatment procedures may require just a single session to produce the desired results, non-ablative treatments usually call for multiple treatments. The number of treatments is usually 4 – 6 spread over a period of 7 – 21 days.  A discussion with a certified and experienced cosmetic laser practitioner will shed light on the treatment plan that best suits each individual case.
