Using an attachment to the equipment, cold laser treatment narrows the laser beam’s concentration. In this case, the beam is reduced to the size of a pinprick. The invisible infrared laser utilized in laser equipment has a frequency of around 780 to 950 nanometers for its cold grade laser beam. Laser beams which can penetrate the skin and perform surgical operations are also available. A laser beam with a higher intensity may penetrate the body more deeply.
