a laser medical probe adapted for direct contact with , or insertion into , tissue undergoing laser treatment . the probe includes a laser energy transmissive surface for emitting radiation from the probe . the probe surface includes a layer of laser transmissive particles for diffusing laser energy passing therethrough and an affixing material for affixing the particles to the probe surface . laser energy emitted from the surface may be coupled into the particles and irregularly refracted and reflected thereby causing a wide laser energy radiation profile . the affixing material and the particles form a tissue contact surface for directly contacting the tissue undergoing treatment . a substantial number of the particles partially extend from the affixing material . the resultant tissue contact surface is rough . the affixing material may be a ceramic bonding agent .
