Lasers vs Near Infrared vs Cold Laser (LED?)

[Guest guest]

Would/can someone help me with the difference. Will put on my Infrared

light page.

I think lasers are in a tube and from what I've read need to be higher

levels to be effecive, otherwise, disperse..

I get the impression though that nearinfrared is a type of laser???? Do

lasers use infrared light for example.. just differently?

I still dont get cold laser and at this point just want to know if Dr.

Cs LED is a type of cold laser (which I am getting I cannot obtain) and

if there are others and what good they do if any if nor Dr. Cs?

My sister's family have used a " laser " or near infrared (it was red)

device at chiropractor that she said helped them immensely with pain

and repair of injuries. Would love to know the similatities and

differenes. I believe this device also operated on Nogier frequencies

and sounds like the lightworks, but they called it a laser. ??

Thank you!!
