A laser generator for laser therapy in the treatment of pain conditions by selective destruction of nociceptive or pain nerves wherein a laser generator that generates a continuous and pulsed laser wavelength between 690 nm to 980 nm that is transmitted fiberopticallv through a laser fiber within a spinal needle to contact areas within a body where pain nerves require destruction through optimal absorption of laser energy by pain nerves without affecting other types of nerves or surrounding tissues.
