Astanza Laser Science Guys Share What LASER Means and How They Work

astanza laser science guys share what laser means and how they work

Did you know that the word “laser” is actually an acronym? Recently, the Astanza Laser Science experts returned to the lab to discuss the fascinating world of lasers and explain what L-A-S-E-R actually stands for, light amplification by stimulated emission of radiation. Join the trio of science experts to gain a deeper understanding of how lasers function and how they’re fired.

Understanding the Light Spectrum

Science Guys, Joshua Walsh and Jordan Hall, kick off the LASER acronym by explaining the first letter, L – which stands for Light. As explained in the video, visible light is part of the electromagnetic spectrum, situated in between radio waves and gamma rays. The visible light found in lasers is optimal for performing aesthetic treatments on the skin.

Within the realm of visible light, there are two different options: polychromatic and monochromatic light. Polychromatic light encompasses a range of wavelengths, resulting in a mix of colors that collectively appear as white light. On the other hand, monochromatic light uses one wavelength, creating the same shape and size of light from beginning to end. Lasers predominantly use monochromatic light, with wavelengths such as 1064 nm, 532 nm, and 694 nm, to treat specific colors in tattoo ink.

Astanza’s Tattoo Removal Lasers

Nick Banda, Astanza’s third Science Guy, explains the attributes of the Astanza Duality, an aesthetic laser device for tattoo removal. The Astanza Duality is a duo wavelength (1064 nm and 532 nm) laser device. The 1064 nm wavelength is infrared light, not on the visible spectrum, making it suitable for targeting darker pigments such as black and brown ink. Meanwhile, the 532 nm wavelength appears green – targeting red, oranges, and other warm ink colors. Since the light is collimated, the laser maintains a consistent shape and size as it travels, creating a safe and precise treatment for all skin types. 

The Astanza Duality Signature, our newly reimagined tattoo removal device, includes these listed features in addition to three pulse modes (Q-switched, Opti-Pulse, and Photo-Thermal), the ability to expand its treatment capabilities with the optional 8 mm DF and 9 mm HC handpieces, and larger spot sizes.

Amplification and Stimulation

Next in the LASER acronym is Amplification and Stimulation. Amplification refers to the process of increasing the intensity of light. Stimulation is closely tied to amplification, with energy needing to be added to the laser system to stimulate the process of light amplification. Energy inputs, such as a voltage mechanism or flashlamps, excite the molecules within the laser, contributing to the amplification process.

The mousetrap analogy explained in the video helps visualize this process. By dropping the initial ball, energy is introduced into the system, stimulating the surrounding balls on the mousetrap – causing a chain reaction that amplifies the energy within the system. 


The second to last letter, E, stands for Emission. When there’s too much energy in a system, the energy gets emitted as a particle of light called a photon. These photons are released together in one single wavelength, creating a beam of light on the laser.


Lastly, Radiation is the fifth letter of the word LASER. As the Science Guys explain, there are two versions of radiation: non-ionizing and ionizing. Ionizing is a powerful radiation with a significant amount of energy that can alter the structure of DNA, leading to health risks such as cancer. Non-ionizing radiation includes energy that we encounter every day, which passes through our DNA and does not change it. Astanza’s laser technology uses non-ionizing radiation, not posing any health risks.
