The growth of the medical laser industry is linked to the rising need for minimally invasive procedures, cosmetic treatments, and increasing eye disorder incidences. Most individuals these days opt for surgeries with faster recoveries, less pain, better bleeding control, increased accuracy, and fewer post-surgery infections.
Albert Einstein first theorized about lasers in 1917. However, it took several years before MASER was created by C.H. Townes and J.P. Gordon at Bell Laboratories. Some people initially thought that it was a solution that would create more problems.
However, laser technology has seen tremendous advancements in the medical, engineering, telecommunication, and manufacturing industries over the years. Today, you can easily find laser equipment from companies like The Laser Trader.
Read on to know how this technology has evolved over the years:
Laser Technology: Landmark Development Of The Mid-20th Century
Most people often group lasers with computers and transistors because they’re all vital inventions of the 20th century. Both grew from conceptual routes and have increased since WWII ended. Their growth is linked to corporate and government investment, physical research, and the increasing numbers of engineers and physicists who develop ideas and equipment.
Before laser technology became more advanced, application developers had to test them and give feedback on what qualities made them practical. As technology continued to advance, lasers also grew.
The Evolution Of MASER To Laser
After the development of MASER in the 1940s, physicists began thinking of how to create higher frequencies. During that period, the millimetre waves and IR were still undeveloped. So, the frequencies had to be jumped to a magnitude of three or four orders to reach the optical range.
After a lot of research, the laser was finally made. However, scientists were still trying to find out how to use active media and to excite the population with this discovery.
Lasers In Medicine
In 1961, Dr Leon Goldman started to research how laser lights can interact with biological systems. Most scientists were interested in applying laser technology to medicine, though they knew it was difficult to control its power output and energy. The poor absorption of the infrared and red wavelengths also made the early experiments consistently fail.
But in 1964, an argon ion laser was created. This laser had a continuous wave of 488nm and was easy to control. Its high hemoglobin absorption also made it ideal for performing retinal surgeries.
The CO2 laser was an improvement to the argon-ion laser. Unlike the argon-ion laser, which emitted 488nm, the CO2 laser could emit a focused 10600nm that was easily manipulated and absorbed by water.
Researchers discovered that CO2 laser beams could scalp tissues like scalpels and result in less bleeding. Its medical use was mainly investigated between 1967 and 1970 by GezaJako and Dr Thomas Polanyi. By the early 1970s, it began being used in gynaecology surgery and ENT.
The Future Of Lasers
Lasers have made it possible to treat diseases and conditions that would previously take longer to treat. Some were even considered untreatable. The medical laser industry’s main focus is currently on how it can be used for hair removal and in vascular lesions treatment. Research is also undergoing in the non-ablative laser resurfacing sector.
