LaserClean uses a laser beam (a beam of focused condensed light) that is projected/pulsed at surface or material. This process is called irradiating. The laser is adjusted to a desired wavelength and output power. The heat or energy of the beam is absorbed. This excites the electrons on the surface or substrate, and the following reaction is called ablation, which simply means the contaminate crimps or shrinks and pops off the surface being cleaned.
Using a laser process allows greater control; or you can service an entire surface or work on layers; you can target very specific areas. For example: intricate, contoured and textured materials and surfaces can be targeted.
Using a laser process offers the benefit of less waste and can be removed via a vacuum immediately.
Albert Einstein first broached the possibility of stimulated emission in a 1917 paper, having turned his attention the year before from general relativity to the interplay of matter and radiation, and how the two could achieve thermal equilibrium. Einstein devised an improved fundamental statistical theory of heat, embracing the quantum of energy. First, Einstein proposed that an excited atom in isolation can return to a lower energy state by emitting photons, a process he dubbed spontaneous emission. Spontaneous emission sets the scale for all radiative interactions, such as absorption and stimulated emission. Atoms will only absorb photons of the correct wavelength: the photon disappears and the atom goes to a higher energy state, setting the stage for spontaneous emission. Second, his theory predicted that as light passes through a substance, it could stimulate the emission of more light.
Charles Townes: It wasn’t until the 1940s and 1950s that physicists found a use for the concept, even though all that was required to invent a laser was finding the right kind of atom, and adding reflecting mirrors to fortify the stimulated emission process by producing a chain reaction. Charles Townes had worked on radar systems during World War II. After the war ended, he turned his attention to molecular spectroscopy, a technique that studies the absorption of light by molecules. Just like radar, molecular spectroscopy bombards the surface of molecules with light and analyzes the scattered radiation to determine the molecule’s structure.
But the technique was limited by the wavelength of the light produced: in this case, the microwave regime of the electromagnetic spectrum. Townes noticed that as the wavelength of the microwaves shortened, the more strongly the light interacted with the molecules, and the more one could learn about them. He thought it might be possible to develop a device that produced light at much shorter wavelengths. The best way to do this, he thought, would be to use molecules to generate the desired frequencies through stimulated emission.
Townes mentioned the idea to a colleague (later his brother-in-law), Arthur Schawlow, who proposed that the prototype laser be fitted with a pair of mirrors, one at each end of the lasing cavity. Photons of specific wavelengths would then reflect off the mirrors and travel back and forth through the lasing medium. By doing so, they would in turn cause other electrons to relax back into their ground states, emitting even more photons in the same wavelength. So only photons in the selected wavelength and frequency range would be amplified. The two men wrote a paper detailing their concept, published in the December 1958 issue of the Physical Review, although they had yet to build a working prototype. They received a patent for their design two years later.
The same year that the first working laser was built by Theodore Maiman at Hughes Aircraft Company. Theodore Maiman: Developed the first successful working laser, constructed in 1960.

LaserClean is a mobile Laser Cleaning business founded by Ed Gledhill and is headquartered in the Greater Toronto Area. Our mission is to unlock the potential of what can be cleaned, restored and prepared in the most effective manner using laser technology.
Our founder is a serial entrepreneur, having been a student painter for two summer seasons he decided to buy his own equipment and take a stab at operating his own small business at the age of 17. After spending some time trying his hand at various industries, Ed found himself at a bank, he spent over a decade there first in the operations department then in International Banking where he worked at testing software. He continued to paint part time while on the hunt for other opportunities.
Leaving the bank was a scary endeavor but the entrepreneurial drive just would not subside. Ed worked with a consultant to determine what industry he would best be suited for. The service industry was the result. Ed purchased a territory and became the Regional Director of an Office Cleaning franchise which he operated for approx. five years, successfully selling not only contracts but 6 franchises in his territory.
Producing immediate, gratifying results has been a driving force and Ed’s true passion. From a $20 book purchased from the Internet he decided to also give Pressure Washing a try. It was soon discovered that there was a lot to learn, but it was fun, yet hard work but most of all the immediate gratification aspect had been fulfilled.
Drawing on Ed’s passion for results, when he discovered that the laser technology existed he immediately knew his skills and passion were a perfect fit for this new technology and new challenge, LaserClean was becoming a reality.
We plan to partner with the top talent in the field to deliver outstanding solutions to our clients. As LaserClean produces exceptional results our planned strategic alliance with various channel partners shall complete an end to end process.
