Abstract: |
To improve the frequency stabilization of laser diode in the laser frequency scanned interferometric metrology, a modified
method is proposed by using a fiber ring resonator. The theoretical analysis of this modified method is performed. Moreover,
the Pound-Drever-Hall (PDH) technique is employed to obtain the frequency discrimination curve of a fiber ring resonator,
whose finesse is 1260 and line-width is 270 kHz. The simulated results show that the curve has a steep slope near the resonant
frequency, which proves the sensitivity of this system to the frequency deviation, so the modified method has great potential
for the frequency stabilization of a laser diode. |
