Which diode should I get? There are so many types?
In a nut shell, the red is more for surface issues and not as effective for deep work. A HeNe can be suitable and affordable. If you need something a little more powerful or looking at something for pain, the GaAs gassed diodes are the most popular. The most expensive type are the GaAiAs gassed diodes that have a wavelength of 750 to 980nm. These are always the pricey ones and are costly to make.
What type of gas is in your diode?
With the right gasses in different wavelengths to create the parameters and the field of infrared can make the difference. It might not be important if someone just wants to get rid of pain but some typically don't have as much lasting effects as the better ones. You might have to use these lasers more often and more times per day but then again, you don't pay as much. The spectrum might lean more toward the near infrared on some beams and more toward the far-infrared beams. Where in this range your laser emits can help determine this. The right parameter of the beam can either accelerate or inhibit. One activates the mitochondria and produces ATP and others don't. Just heat. Know the gas type before buying.
Gas Scams: People should really know more about the type of gas in their laser before buying one. Forget the brands, studied gasses first or know someone who has studied them. If you want to treat the lower back and go deep, the type of gas needed for this will make the laser beam super dense and go deep with a huge spread, usually the 830nm to 900+nm range. If you are treating an elbow or hand and don't need to go bone deep, you can get away with a cheaper gas, maybe the gasses used in the 600nm to 700nm category. The more intricate the laser, usually the more expensive the gas is to make that type of diode.
Update: I will not sell lasers that are not FDA cleared. Too many doctors have gotten sued since I started this site. I will let everyone know which lasers are now approved
I will never trash talk lasers that did not get approved or those that were never cleared with the FDA. See my requirements for lasers that are not FDA cleared.
