1. A therapeutic system comprising:

  • a light source generating an output optical beam, comprising;

    a plurality of semiconductor sources generating an input optical beam;

    a multiplexer configured to receive at least a portion of the input optical beam and to form an intermediate optical beam; and

    one or more fibers configured to receive at least a portion of the intermediate optical beam and to form the output optical beam, wherein the output optical beam comprises one or more optical wavelengths, and wherein at least a portion of the one of more fibers is a fused silica fiber with a core diameter less than approximately 400 microns;

    an interface device configured to receive a received portion of the output optical beam and to deliver a delivered portion of the output optical beam to a sample, wherein the interface device comprises one or more lenses to focus at least a part of the delivered portion of the output optical beam on the sample, and wherein the interface device further comprises a surface cooling apparatus to reduce damage to a top surface of the sample; and

    wherein at least the part of the delivered portion of the output optical beam penetrates into the sample a depth of 1.5 millimeters or more, wherein at least some of the part of the delivered portion of the output optical beam is at least partially absorbed in the sample to thermally damage at least a part of the sample, and wherein the output optical beam comprises a fluence less than about 250 Joules per centimeter squared.
