There rniaht be also an additional component of more dificulty in controlling the thermal effects. We have to remembers however. For some time alreadv, an ongoing debate has ensued concemulg possible advantaoes and disadvantages of continuous versus pulse mode lasers. Several studies suggest the possible superiority of one svstem over the other in a specific experimental design, others vielded similar results. From a clinical standpoint however no firm conclusions can be drawn in part, due to the nonuniformity in design of the research protocols.
Technological advances permit more readily achievable various tunable lasers.
The advantages of laser based devices are obviouslv the hiash potential energv output more precise tunability of the wavelength and the possibilitv of coupling to various accessories. Emitting Diodes Technolooical advances are now reaching a level where sufficient ponver OtltpUt can be expected from newer LED devices. Several presentations at this meeting will deal With I F.lds which can be tamed to wavelengths between 650 and 700 nm. These types of devices also permit the development of many other wavelengths. Light in all its various forms and wavelengths is onlv one part of the electromagnetic spectrum.
