The present invention provides a laser system and laser handpiece and process for skin treatment. The system includes components for producing a continuous or pulse laser beam, and components for delivering a substance to the damaged region of skin. The system is designed to control and utilize the laser beam for damaging small volume of skin tissue and using a disposable tip to deliver a substance which is applied simultaneously or with some delay producing a combination of laser action with the action of a named substance at the same time.

Laser filler

A laser skin treatment process and system. The system includes features for producing a first laser beam of long pulse duration and a second laser beam of short pulse duration and a skin cooler for cooling the surface of a region of skin. The system is designed to utilize the first laser beam for heating a volume of skin tissue below the cooled surface region to a temperature to produce skin tissue modification but below skin tissue damage threshold. This volume of skin tissue is called a 'thermal cavity'. The second laser beam is divided into a plurality of separate laser beams that are directed through separate optical fibers and via separate paths through skin tissue to a single tiny volume of skin tissue within the thermal cavity to produce in that tiny volume mechanical damage. This tiny volume is called an energy droplet. Thus tiny regions of tissue are damaged while minimizing or preventing any significant damage to adjacent tissue.

Skin treatment system with time modulated laser pulses

Providing a high peak power short pulse duration gas discharge laser output pulse comprises a pulse stretcher a laser output pulse optical delay initiating optic diverting a portion of the output laser pulse into an optical delay having an optical delay path and comprising a plurality of confocal resonators in series aligned to deliver an output of the optical delay to the laser output pulse optical delay initiating optic. The plurality of confocal resonators comprises four confocal resonators comprising a twelve pass four mirror arrangement. An apparatus and method may comprise a plurality, e.g., two pulse stretchers in series and may include spatial coherency metrology.

Laser output light pulse stretcher

A beam delivery unit and method of delivering a laser beam from a laser light source for excimer or molecular fluorine gas discharge laser systems in the DUV and smaller wavelengths is disclosed, which may comprise: a beam delivery enclosure defining an output laser light pulse beam delivery pat from an output of a gas discharge laser to an input of a working apparatus employing the light contained in the output laser light pulse beam; a purge mechanism operatively connected to the beam delivery enclosure; an in-situ beam parameter monitor and adjustment mechanism within the enclosure, comprising a retractable bean redirecting optic; a beam analysis mechanism external to the enclosure; and, a retraction mechanism within the enclosure and operable from outside the enclosure and operative to move the retractable beam redirecting optic from a retracted position out of the beam path to an operative position in the beam path. The BDU may also include a beam attenuator unit contained within the enclosure adjustably mounted within the enclosure for positioning within the beam delivery pat. The BDU may have at least two enclosure isolation mechanisms comprising a first enclosure isolation mechanism on a first side of the enclosure from the at least one optic module and a second enclosure isolation mechanism on a second side of the enclosure from the at least one optic module, each respective enclosure isolation mechanism comprising a flapper valve having a metal to metal seating mechanism and a locking pin assembly. A precision offset ratchet driver operative to manipulate actuator mechanisms in difficult to reach locations may be provided. An external kinematic alignment tool may be provided. A method of contamination control for a BDU is disclosed comprising selection of allowable materials and fabrication processes.

Gas discharge laser light source beam delivery unit

A laser system and process by which prior art medical and cosmetic laser techniques using laser beams chosen to produce selective thermolysis are enhanced by the addition of a second laser beam chosen for much deeper transmission in tissue and more uniform absorption. Preferred embodiments include enforcement with a 1079 nm YAP:Nd laser beam of a 532 nm beam produced by a frequency doubled YAG:Nd laser beam.
