Claim 14:
15. An ophthalmic laser surgery system comprising:
a laser engine capable of generating a femtosecond laser beam for surgical procedure;
an integrated 3D laser scanning system;
a laser scanning confocal microscope (LSCM) subsystem, comprising:
(a) a laser source capable of delivering a low peak power laser beam for LSCM measurements, wherein the femtosecond laser beam has an engine wavelength and the low peak power laser beam has a scan wavelength, and the scan wavelength is substantially the same as the engine wavelength;
(b) a beamsplitter in line with the lower peak power laser beam;
(c) a first, far field diagnostics module configured to receive back-reflected light from a patient's eye or other target directed by said beamsplitter;
(d) a second, near field laser beam diagnostics module;
a laser beam guide configured to focus a received laser beam for output;
a fixed mirror and, said second, near field diagnostic module being in communication with said fixed minor; and
a reconfigurable optical device being configured for positioning in a first position and in a second position in order to selectively engage either the generated femtosecond laser beam of the femtosecond laser engine or the low peak power laser beam of the LSCM subsystem,
wherein the reconfigurable optical device is configured such that, in the first position, the reconfigurable optical device optically engages with the generated femtosecond laser beam such that said reconfigurable optical device is in line with a path of the generated femtosecond laser beam generated by the femtosecond laser engine which is configured to direct the generated femtosecond laser beam into the laser beam guide, and wherein the reconfigurable optical device is configured to deny entry of the low peak power laser beam of the laser source into the laser beam guide; wherein, in the second position, the reconfigurable optical device is configured such that the reconfigurable optical device is out of alignment with the generated femtosecond laser beam and thus the generated femtosecond laser beam is denied entry into the laser beam guide and wherein, in the second position, the low peak power laser beam is directed into the laser beam guide so that at least some of the back-reflected light from the patient's eye or other target which returns back through the laser beam guide is directed onto said first, far field diagnostics module to at least measure an intensity of the back-reflected light from the low peak power laser beam;
wherein the second, near field laser beam diagnostics module is configured to be in optical communication with the laser engine such that when the reconfigurable optical device is in the first position, at least a small portion of the generated femtosecond laser beam engages with said second, near field laser beam diagnostics module and provides real time information on operational status of the generated femtosecond laser engine during the surgical procedure; and
wherein said second, near field diagnostic module is positioned to receive a first beam sample which leaks through the reconfigurable optical device in its first position and said fixed minor also being configured to partially reflect a second beam sample onto the reconfigurable optical device in its first position such that the reconfigurable optical device reflects the second beam sample to the first, far field diagnostics module, such that data from said reflected second beam sample is utilized during the surgical procedure.
