Add to ORKGA novel distributed-feedback (DFB) fiber laser hydrophone with an acoustic low-pass filter is presented. An aluminous cover with an orifice in the center is used to eliminate high-frequency acoustic components. The acoustic pressure response is theoretically analyzed based on an electro-acoustic method. Two types of hydrophones of this kind have been fabricated and tested. The experimental results over the range of 10 to 2000 Hz are in good agreement with the theoretical expectations
