Abstract

Provided are a device () and a method for online measuring a spectrum for a laser device. The device () for online measuring a spectrum for a laser device includes: a first optical path assembly (G) and a second optical path assembly (G), and the second optical path assembly (G) and the first optical path assembly (G) constitute a measurement optical path. The second optical path assembly (G) includes: an FP etalon () and a grating (). The homogenized laser beam passes through the FP etalon () to generate an interference fringe. The grating () is arranged after the FP etalon (), or is arranged before the FP etalon () in the measurement optical path, and is configured to disperse the laser beam passing through the FP etalon ().
