A surgical laser tool for performing a laser procedure at a treatment site comprising: a laser source configured to generate laser energy; a fiber catheter comprising at least an imaging fiber and a laser fiber; a diagnostic light source configured to deliver light to the imaging fiber through an optical path, wherein the fiber catheter comprises an imaging channel that receives the imaging fiber configured to acquire optical feedback from the treatment site and a laser channel that receives the laser fiber configured to deliver the laser energy to the treatment site from the laser source, the imaging channel being separate from the laser channel, and a magnetic force actuator or piezoelectric actuator configured to move or vibrate a distal end of the imaging fiber within the imaging channel for scanning purposes, wherein the imaging fiber is configured to deliver the diagnostic light to the treatment site from the diagnostic light source in a first direction parallel to a longitudinal axis of the fiber catheter, and wherein the laser fiber is configured to deliver the laser energy to the treatment site from the laser source in a second direction parallel to the longitudinal axis of the fiber catheter, the surgical tool further comprising an analytical device configured to analyze the optical feedback in form of reflected light from the treatment site in order to allow a physician to perform a diagnosis on the treatment site. a laser source configured to generate laser energy; a fiber catheter comprising at least an imaging fiber and a laser fiber; a diagnostic light source configured to deliver light to the imaging fiber through an optical path, wherein the fiber catheter comprises an imaging channel that receives the imaging fiber configured to acquire optical feedback from the treatment site and a laser channel that receives the laser fiber configured to deliver the laser energy to the treatment site from the laser source, the imaging channel being separate from the laser channel, and a magnetic force actuator or piezoelectric actuator configured to move or vibrate a distal end of the imaging fiber within the imaging channel for scanning purposes, wherein the imaging fiber is configured to deliver the diagnostic light to the treatment site from the diagnostic light source in a first direction parallel to a longitudinal axis of the fiber catheter, and wherein the laser fiber is configured to deliver the laser energy to the treatment site from the laser source in a second direction parallel to the longitudinal axis of the fiber catheter, an imaging channel that receives the imaging fiber configured to acquire optical feedback from the treatment site and a laser channel that receives the laser fiber configured to deliver the laser energy to the treatment site from the laser source, the imaging channel being separate from the laser channel, and a magnetic force actuator or piezoelectric actuator configured to move or vibrate a distal end of the imaging fiber within the imaging channel for scanning purposes, wherein the imaging fiber is configured to deliver the diagnostic light to the treatment site from the diagnostic light source in a first direction parallel to a longitudinal axis of the fiber catheter, and wherein the laser fiber is configured to deliver the laser energy to the treatment site from the laser source in a second direction parallel to the longitudinal axis of the fiber catheter, the surgical tool further comprising an analytical device configured to analyze the optical feedback in form of reflected light from the treatment site in order to allow a physician to perform a diagnosis on the treatment site.
