    Abstract: The present disclosure relates to a method and a device for controlling a laser output. According to an embodiment, there are provided a method for controlling a laser output of a laser device, provided with a laser generator and a handpiece for radiating a laser generated at the laser generator onto a target, and a device performing the method. The method includes the steps of: measuring, by a plurality of distance sensors arranged along a circumference of one end of the handpiece from which the laser is outputted, distances between the plurality of distance sensors and the target; based on the distances between the distance sensors and the target, calculating an effective area which is a region of the target onto which the laser is really radiated; and increasing or reducing the laser output to radiate the laser onto the effective area with a predetermined energy density.

    Abstract: According to an embodiment of the present disclosure, a non-transitory computer readable storage medium which stores one or more non-discrete spectrum analysis programs for lesion tissue detection based on laser spectroscopy is provided. The one or more programs cause an electronic device provided with one or more processors to execute a lesion tissue detection method, and the lesion tissue detection method includes a step of determining whether there is lesion tissue by applying a lesion tissue detection learning model to a result of non-discrete spectrum measurement. The result of the non-discrete spectrum measurement is a result of measuring spectra of all generated light that is generated from a time when a laser is projected onto a sample until the generated light is no longer generated.

    Abstract: According to one embodiment, a system for diagnosing a pigmented lesion is provided. The system includes: a sound detector configured to detect a photoacoustic wave which is generated when a first laser is irradiated onto a target having a pigmented lesion; a disease diagnosis unit configured to determine a type of the pigmented lesion based on generated light which is generated when a second laser is irradiated onto the target; and a pigmented lesion diagnosis unit configured to calculate at least one of a depth and a thickness of the pigmented lesion based on a time at which the photoacoustic wave is detected and laser irradiation time information on the first laser irradiated onto the target.
