Title: Control unit for laser diode oscillation wave length
Inventor: KANEDA TETSUYA
IPC: H01S5/065
Filed: 1978-06-02
Abstract: PURPOSE:To hold the oscillation wavelength of the laser beams at a constant level substantially by putting again part of the laser output beam to the laser and controll- ing the phase of feedback light. CONSTITUTION:With application of the voltage obtained by piling the micro-AC component vp onto DC voltage Vp to piezo-element 6, reflector 5 has minor vibra- tions in the direction of the optical axis. Thus, the oscillation wavelength of laser element 4 distant by distance d has a small and linear variation to d in the half- wave cycle. Voltage vp is set so that the fluctuation width may be within the linear  range, and the transmission width of filter 10 is reduced sufficiently.  Thus, the  beams enter PIN diode 1 via Selfoc lens 9 and reflector 11. When the product of the AC component of the output of diode 1 and voltage vp is fed back to power source 12, the laser oscillation wavelength can be fixed to the central wavelength of filter 10. The more stability obtained the smaller the transmission width of the filter.
