    "abstract": "We demonstrate a fiber Fabry-Perot (FFP) sensor capable of detecting\nsub-picostrain signals, from 100 Hz and extending beyond 100 kHz, using the\nPound-Drever-Hall frequency locking technique. A low power diode laser at 1550\nnm is locked to a free-space reference cavity to suppress its free-running\nfrequency noise, thereby stabilizing the laser. The stabilized laser is then\nused to interrogate a FFP where the PDH error signal yields the instantaneous\nfiber strain.",
