Title: Method and apparatus for stabilizing frequency for laser diode
Inventor: HERUMUUTO HANSU TERU
IPC: H01S5/068
Filed: 1994-04-25
Abstract: PURPOSE: To keep frequency constant by generating a phase variable rectangular wave from a modulation signal generated from a signal generator, dividing an output current from a photodiode to two intervals each responsive to a half cycle of the rectangular wave, and thereafter integrating the divided currents. CONSTITUTION: Temperature of a laser diode 10 is adjusted such that radiation frequencies of light from the laser diode 10 are existent from a lower to upper side of four second transition lines of rubidium. Then, an electronic cooling device is adjusted to alter the frequency of the light radiated from the laser diode 10 until one of the four transition lines in a rubidium cell 20 is excited. A saw-toothed AC current is supplied to a Zeeman coil 38 from a signal generator 36. An oscillating magnetic field is generated with the aid of the signal generator 36 and the Zeeman coil 38, with which magnetic field each of the second transition lines is divided periodically following the direction of an individual electron spin.
