Title: Frequency-stabilizing method for internal mirror laser by magnetic modulation
Inventor: SETA KATSUO
IPC: H01S3/139
Filed: 1984-06-05
Abstract: PURPOSE:To obtain the laser of low cost excellent in the reproducibility of frequency absolute values by a method wherein an AC magnetic field of modulation frequency is generated in a laser tube with a coil heater, and the laser tube length is thermally controlled on modulation signals strong in the output generated thereby. CONSTITUTION:The coil heater 2 is wound around an internal mirror laser tube 1. The laser tube generates photo beams of approx. 1/10 of the output formward normally backward. This weak photo beam or part of the output light from forward is introduced t a polarizing plate 3. The polarizing plate 3 adjusts its direction of transmission so as to come incident with the direction of polarization on a specific mode. If the laser tube oscillates only on vertical modes 1-2, the light transmitting through the polarizing plate 3 at this time is only of single vertical mode. Its intensity is converted into an electric signal by a photo detector 4 and inputted to a synchronizing detector 6. This detector 6 detects in phase synchronization only the component of a modulation frquency (f) given by an oscillator 5. A signal detected in synchronization is supplied with a suitable multiplication factor and a suitable time constant by a control signal processor 7 and inputted to a heater-power control circuit 8.

Abstract: PURPOSE:To obtain a semiconductor substrate which does not allow generation of crack to the entire part of the desired region by forming the MESA line having the indented stepwise sectional view to a first compound semiconductor crystalline layer and then forming thereon a second compound crystalline layer. CONSTITUTION:After a first GaAs layer 2 is formed on a Si substrate 1, a stepwise MESA etching is carried out to form a GaAs stepped part 6 on the first GaAs layer 2. Thereafter, sagged GaAs stepped part 7 is formed by generating a sagging part to the stepped portion 6. Thereafter, a second GaAs layer 4 is grown. Thereby, since the MESA part is formed stepwise even when a thick GaAs part 5 is generated, it becomes very thin and therefore crack is not easily generated.
