Claim 13:
14. A method of mapping and excising a tumor embedded in non-tumorous biological tissue, comprising:
generating, by a dye laser system, a dye laser beam by using an intracavity quenching technique applied to a mixture of sample non-tumorous biological tissue and probe ions being of a single type of ion, so that the dye laser beam has wavelengths that excite probe ions bound to a tumor but do not excite probe ions bound to non-tumorous biological tissue, each probe ion in the mixture having an absorption bandwidth that does not exceed a narrowness threshold bandwidth amount and having an absorption wavelength peak that shifts based on a local binding environment, the sample non-tumorous biological tissue being initially in a body of a living being and in a proximity to a tumor in the body, and the sample non-tumorous biological tissue being extracted from the body and placed in the dye laser system;
emitting, by the dye laser system, the dye laser beam within the body;
injecting, by an injection system, a solution of probe ions in front of the dye laser beam to bind a first portion of the probe ions in the solution to the tumor in the body and a second portion of the probe ions in the solution to non-tumorous biological tissue in the body, the probe ions in the solution being in a concentration matching a concentration of the probe ions in the mixture to which the intracavity quenching technique is applied;
exciting, by the dye laser beam, the probe ions bound to the tumor, without exciting the probe ions bound to the non-tumorous biological tissue in the body;
detecting, by a detector, an emission of radiation generated by the excitation of the probe ions bound to the tumor;
identifying, by the detector, boundaries of the tumor based on the detected emission of radiation; and
cutting, by a surgical cutting laser, tissue in the body in a proximity to the identified boundaries of the tumor by using a cutting beam generated by the surgical cutting laser.
