Provided are a spectrometer using a laser and a spectroscopic method using a laser. A spectroscopic apparatus using a laser is a spectroscopic apparatus using a laser, comprising: a laser unit for emitting a laser, focusing on a sample, a gas pulse unit for injecting a gas pulse for providing an atmospheric gas for a predetermined time period around the sample, and a sample And a control unit for detecting a light emission of the plasma generated by the laser and a control unit for providing a control signal for controlling the laser unit and the gas pulse unit. Therefore, the plasma spectral signal can be increased, and the analysis performance can be improved by increasing the spectral signal. In particular, it is possible to implement a spectroscopic device relatively easily, and to implement a spectroscopic device that can analyze a sample in real time in the field. |
