A laser generator for laser therapy in the treatment of pain conditions by selective destruction of nociceptive or pain nerves, where a laser generator that generates a continuous and pulsed wavelength that is transmitted fiber-optically through a laser fiber within a spinal needle to contact areas within a body where pain nerves require destruction through optical absorption of laser energy by pain nerves without affecting other types of nerves or surrounding tissues. The laser generator can be used for treatment in humans, small animals and also large animals, which can receive pain relief without adverse effects.
