Dermatological systems and methods for reducing pain associated with treating of skin with high-fluence therapeutic laser light including applying a first agent to solubilize oils, removing the first agent and oil to reduce the level of oil in the skin by at least 85%, rehydrating the skin after the oil removal, applying a contact cooling element including a cooling window to the area within five minutes of rehydrating the skin, cooling the skin from a first to a second temperature, and applying at least one high-fluence therapeutic laser pulse to the skin.

Methods of skin treatment with laser light

Dermatological systems and methods for providing a therapeutic laser treatment using a handpiece delivering one or more therapeutic laser pulses to a target skin area along a first optical path, and sensing the temperature of the target skin area based on infrared energy radiating from the target skin area along a second optical path generally counterdirectional to the first optical path, and sharing a common optical axis with the first optical path for at least a portion of the first and second optical paths. The handpiece may also provide contact cooling for a first skin area comprising the target skin area.

Dermatological systems and methods with handpiece for coaxial pulse delivery and temperature sensing

Dermatological systems and methods for providing a therapeutic laser treatment of tissue having poor chromophore selectivity using a laser source having a grating element to provide laser light having reduced linewidth. In some embodiments, the linewidth is reduced by at least half compared to the linewidth that would be provided in a system without the grating filter element. The linewidth may be reduced in some cases to 500 GHz or less, 300 GHz or less, or 200 Hz or less.

In some embodiments, multiple OPOs may be provided to enable a wide range of selectable treatment wavelengths.

Dermatological laser treatment systems and methods using optical parametric oscillator

Dermatological systems and methods for providing a therapeutic laser treatment wherein the duration of a therapeutic laser pulse is based on one or more determinations of a surface temperature of the skin during the delivery of the pulse. Initiation of the therapeutic laser pulse may be based on sensed skin temperature during a cooling of the skin prior to initiation of the pulse.

Systems and methods for controlling therapeutic laser pulse duration

Dermatological systems and methods for providing picosecond laser pulses at a plurality of treatment wavelengths, wherein at least one of the wavelengths is provided by an optical parametric oscillator (OPO) capable of providing picosecond laser pulses at a wavelength for treating one or more target tissue types such as a sebaceous gland, sebum, or collagen.

An imaging-based laser system can include a laser-beam system, configured to generate and scan a beam of laser pulses with an adjustable laser-power parameter to points of a scan-pattern in an eye, and an imaging-based laser-controller, configured to image a layer in the eye, to control the scanning of the beam of laser pulses to the points of the scan-pattern, and to control a laser-power parameter of the laser pulses according to the distance of the points of the scan-pattern from the imaged layer.

Imaging-controlled laser surgical system

Techniques, apparatus and systems for laser surgery including imaging-guided surgery techniques, apparatus and systems.

Precise targeting of surgical photodisruption

Designs and techniques for constructing and operating femtosecond pulse lasers are provided. One example of a laser engine includes an oscillator that generates and outputs a beam of femtosecond seed pulses, a stretcher-compressor that stretches a duration of the seed pulses, and an amplifier that receives the stretched seed pulses, amplifies an amplitude of selected stretched seed pulses to create amplified stretched pulses, and outputs a laser beam of amplified stretched pulses back to the stretcher-compressor that compresses their duration and outputs a laser beam of femtosecond pulses. The amplifier includes a dispersion controller that compensates a dispersion of the amplified stretched pulses, making the repetition rate of the laser adjustable between procedures or according to the speed of scanning. The laser engine can be compact with a total optical path of less than 500 meters, and have a low number of optical elements, e.g. less than 50.
