英文摘要 | PURPOSE:To obtain a compact laser wavelength stabilizer characterized by simple adjustment, by inputting part of the output light of a semiconductor laser into an optical fiber passing a standard material, and utilizing the absorption of the part of the light propagating through the fiber. CONSTITUTION:The output of a temperature controlled laser LD1 is propagated through a fiber FB1 and split in a fiber coupler CP One beam is sent to the outside as output light 1 The other beam is inputted into a waveguide type acoustooptic modulator UM2 through a fiber FB3. The modulated light is propagated through FB4 and passes an absorbing cell CL2. The propagating light leaks out of a core (a) of the FB4 in the cell. The electric field at this part mutually reacts with Cs gas at the outer surface, and absorption occurs at a specified wavelength. When the output of the fiber FB4 is detected by PD1, an absorption signal is obtained. The signal is fed back to the laser LD1 through a lock-in amplifier LA The oscillating frequency of the laser can be controlled in the vicinity of the center of the absorption. Position alignment is not required, adjustment is simple and the compact configuration can be implemented. |
