Abstract

The invention relates to a laser device, comprising a laser material (1) brought into a simmer mode. A controllable source (7, 17) of additional energy (16, 20) supplies energy to the laser material (1), such that in only a desired part of the laser material (1) a lasing threshold is exceeded, and a laser beam (10) is emitted from only a desired part of the laser surface. This device makes possible to provide a laser beam in just the desired part of the laser, which allows a flexible and localized output. The invention further relates to a hair- removing device comprising a laser device according to the invention and further comprising an optical system(6) for focusing the laser beam pulses on a focal spot (12) and for positioning the focal spot in a target position, wherein the optical system (6) comprises a movable lens or a plurality of individually addressable lenses.

Description

technical field [0001] The invention relates to a method and a device for generating laser pulses. [0002] The invention also relates to a hair removal device using such a method and / or device. Background technique [0003] Methods of generating laser pulses are well known. In general, they involve generating population inversion in suitable materials so that stimulated emission can occur, and further increasing the intensity by reflecting the generated radiation between mirrors in the laser cavity. Such lasers may also be pump lasers and pulsed lasers capable of generating very short and intense pulses of radiation. [0004] One of the drawbacks of lasers and laser beam generation as mentioned above is that it is rather inflexible as far as the beam is concerned. In fact, there is no or at most variable power, repetition rate and / or frequency. Contents of the invention [0005] It is an object of the present invention to provide a method and a device for generating a...
