A fractional handpiece and systems thereof for skin treatment include a passively Q-switched laser assembly operatively connected to a pump laser source to receive a pump laser beam having a first wavelength and a beam splitting assembly operable to split a solid beam emitted by the passively Q-switched laser assembly and form an array of micro-beams across a segment of skin. The passively Q-switched laser assembly generates a high power sub-nanosecond pulsed laser beam having a second wavelength.

A pigment treatment system includes a handheld apparatus to receive a sub-nanosecond laser beam with a wavelength of about 480 nm to about 550 nm and output a sub-nanosecond laser beam with a wavelength of about 700 nm to about 740 nm. The handheld apparatus includes a monolithic crystal with a first surface coating and a second surface coating to facilitate the change in wavelength of the laser beam through the crystal.

Pigment treatment system and methods of use thereof

A MOPA laser system that includes a seed laser configured to output pulsed laser light, an amplifier configured to receive and amplify the pulsed laser light emitted by the seed laser; and a pump laser configured to deliver a pump laser beam to both the seed laser and the amplifier and a variable attenuator configured to eliminate missing Q-switched pulses.

Laser systems and related methods

A microchip laser and a handpiece including the microchip laser. The microchip laser includes a laser medium with input and output facets. The input facet is coated with a highly reflective dielectric coating at microchip laser wavelength and highly transmissive at pump wavelength. The output facet is coated with a partially reflective at microchip laser wavelength dielectric coating. A saturable absorber attached by intermolecular forces to output facet of microchip laser. A handpiece for skin treatment includes the microchip laser.

Disclosed is an apparatus and a method to preserve linearly polarized laser beam when it passes through a freely twisting beam delivery system such as an articulated arm. The polarization of the output beam from the delivery system will be stable and the same as the polarization of the input beam to the delivery system, and can be used to pump anisotropic laser crystals as well as nonlinear optical crystals.

Laser system preserving polarization through a freely movable beam delivery system

A MOPA laser system that includes a seed laser configured to output pulsed laser light, an amplifier configured to receive and amplify the pulsed laser light emitted by the seed laser; and a pump laser configured to deliver a pump laser beam to both the seed laser and the amplifier.

Laser systems and related mehtods

Disclosed is an applicator or handpiece configured to apply treatment energy to a segment of skin located in a tissue or skin treatment plane. The treatment energy could be RF energy, applied by a pair of bipolar RF electrodes or optical energy. The applicator includes an optical system configured to form a rectangular spot and homogenize the optical energy distribution.

Applicator

A device for reducing spontaneous emission in laser oscillator laser amplifier laser system.

Device for reducing optical feedback into laser amplifier

An apparatus for treating a subcutaneous fat region is provided. The apparatus includes a housing that has a skin contacting portion defining a chamber. The apparatus also includes a first spaced region in the housing through which a coolant passes and a second spaced region in the housing that is at least partially evacuated of air. The apparatus further includes a source of electromagnetic radiation, a source of vacuum in fluid communication with the chamber, and a source for the coolant.
