The present application relates to the field of optical fiber laser devices. Disclosed are an optical fiber laser device protection method and an optical fiber laser device. The method comprises: determining a working state of a pumping source; when the working state of the pumping source is a state of having output a laser, acquiring a detection signal, wherein the detection signal is used for indicating a transmission state of the laser being transmitted in an optical fiber; and generating protection information when the detection signal satisfies a preset protection condition. A light emission situation of a pumping source is detected by means of detecting a current signal in the pumping source, a detection signal is acquired after the pumping source normally outputs a laser, and protection information is quickly generated when the detection signal satisfies a preset protection condition, such that the degree of damage of an optical fiber laser device is reduced.
