A new therapeutic light source being developed in Israel may ultimately replace many of the aesthetic laser devices currently used. The device, known as Traser (Total Reflection Amplification of Spontaneous Emission of Radiation), “is not a laser and it’s not an intense pulsed light,” Dr. Christopher Zachary said at the SDEF Summit in Aesthetic Medicine sponsored by Skin Disease Education Foundation (SDEF). “No photons come from the flash lamps. It’s one device with many wavelengths. It’s tunable, has a high peak power, and has variable pulse duration from 0.45 to 100 milliseconds,” he said.
The Traser contains a “dye cell” (an internally reflecting body that hosts a fluorescent dye), one rear mirror, flashlamps above and below, an output waveguide, and a reflector cavity that houses the device. The Traser is the brainchild of Morgan Gustavsson, a pioneer of intense pulsed-light technology. It was first described in the peer-reviewed online journal PLoS ONE.
