Laser output limiting device

A method of using a laser output limiting device, comprising:

• providing a laser output limiting device including:
• a reflecting device arranged in an optical path of a laser beam of a predefined wavelength,
• a switching layer which comprises a material exhibiting a metal-insulator transition,
• a reflecting layer which is positioned downstream of the switching layer in the optical path of the laser beam, and
• wherein the reflecting device is configured such that an output of the laser beam when it is incident upon the reflecting device which exceeds a predefined threshold causes a change in the refractive index of the material in the switching layer, and an output of the laser beam reflected by the reflecting device is thus reduced as compared to the output of the laser beam when it is incident upon the reflecting device due to reduced reflection by the reflecting device;
• and
• using the laser output limiting device in a laser spectroscopy device.
