LASER COMPONENTS GmbH (LCG) is celebrating 30 years of laser optics production. When LCG entered the laser market by producing high damage thresholds laser optics, lasers were rapidly penetrating medical use in many surgical specialties.
The First Medical Laser. A laser was first used in medicine in 1961: At the Columbia Presbyterian Medical Center in Manhattan, Dr. Charles J. Campbell, et al., used a ruby laser to destroy a tumor on a patient’s retina .
The ruby laser was also used by Dr. Leon Goldman, who published studies on the effect of laser beams on the skin in 1963  and used the beam to remove tattoos. He began his research in 1960 and is considered the “Father of Laser Medicine in the United States“.
Medical Lasers Today. Modern laser applications are numerous with fantastic capabilities. For example, optogenetics involves the use of light to control cells in living tissue, typically neurons, with the potential to treat disorders like addiction, Parkinson’s disease, depression and cancer. Or to name a few others: laser-assisted drug delivery through skin, fiber lasers at various wavelengths for femtosecond micromachining of hard and soft tissues, laser spectroscopic techniques like fluorescence or Raman for cancer detection and imaging. But that’s not all. Lasers for bio stimulation, triggering growth and pain control are moving to clinical proof, paving the way for more innovations.
Lasers have changed over the years to meet physician and patient treatment demands. In this edition of Photonics News, three industry experts share their experience on material processing of medical components, the effect of laser radiation on tissue, eye surgery and laser light in tattoo removal.
And don’t miss our product release overview for SPIE Photonics West, at the end. The leading event on photonics promises to become the highlight of the year with the release of QuickSwitch® Pulsed Laser Diodes having pulse duration of 2.5ns, 1.41 higher D* for pyroelectric detectors, advances in extended InGaAs detectors, custom patterned polarizers, improved 808nm fiber-coupled diode lasers, specialized laser diode drivers, extended portfolio of FLEXPOINT® laser modules, and many more.
