Summary: | The invention relates to a hydrogen sensing head based on a distributed feedback fiber laser as well as a preparation method and application thereof. The hydrogen sensing head based on the distributed feedback fiber laser comprises a hydrogen sensitive distributed feedback fiber laser (1) (hydrogen sensitive DFB-FL and DFB-FL1) and a temperature compensation distributed feedback fiber laser (2) (temperature compensation DFB-FL and DFB-FL2), the hydrogen sensitive distributed feedback fiber laser (1) is connected with the quartz substrate (3); the temperature compensation distributed feedback fiber laser (2) is connected with the quartz substrate (3); and the hydrogen sensitive distributed feedback fiber laser (1) is coated with a hydrogen sensitive material. Compared with the prior art, the hydrogen sensing head has the advantages of high sensitivity, high precision, electromagnetic interference resistance, low detection limit, long-term stable monitoring and the like.
