The invention relates to a stabilized lidar system and method for stabilization. The invention describes a laser radar system comprising a laser (10), the laser (10) being designed to emit monochromatic laser radar radiation in a wavelength operating range; a thermal element (20) provided for adjusting the operating temperature of the laser (10); a device (22) for evaluation, which is designed todetermine a degree of deviation of an actual wavelength of the radiation from a desired wavelength within a wavelength operating range of the laser (10) from the radiation emitted by the laser (10); and a device (24) for adjustment, and a control device (22) which is designed to control the thermal element (20) in accordance with a deviation scale determined by the evaluation device (22) in such away that the operating temperature of the laser (10) is adjusted to a value in which the emitted monochromatic laser radar radiation corresponds to the desired wavelength. 本发明涉及一种经稳定化的激光雷达系统和一种用于稳定化的方法。本发明描述一种激光雷达系统，其包括激光器(10
