Patent JP-S6360583-A (JP)
Title: Semiconductor laser
Inventor: UENO SHINSUKE
IPC: H01S5/00
Filed: 1986-08-29
Abstract: PURPOSE:To enable a large optical output oscillator by a concentric circular light source by forming a guide layer with a guiding mechanism near both reflecting surfaces, reducing a spreading angle in the direction vertical to an active layer of laser oscillation beams and shaping a positive index guiding mechanism in the horizontal cross direction of the active layer. CONSTITUTION:An active layer 13 is connected to a guide layer 15 through a second clad layer 14 in the vicinity of both reflecting surfaces in the longitudinal direction of a resonator. The guide layer is connected in predetermined layer thickness extending over the overall length of the resonator. Consequently, beams spread extending over the guide layer from the active layer at the central section of the resonator in the vertical direction, and expand and proceed extending over striped groove width in the hgorizontal cross direction, and the greater part of beams pass through the second clad layer 14 and forward move into the guide layer in the vicinity of both reflecting surfaces. Since the band gap of the guide layer extends by 157meV or more to laser oscillation beams, beams advance without loss in the guide layer in the vicinity of both reflecting surfaces, and beams reflected by the reflecting surfaces efficiently enter the active layer at the central section of the resonator and are re-excited, thus allowing laser oscillation at a low threshold with high efficiency.

Now, the respective temp. curves of the object to be treated (a) having a large carburization area, (b) having a middle carburization area and (c) having a small carburization area, have a specified relation according to the varying sizes of said carburization areas. More specifically, for the case (a) the temp. drop until the equil. point of the furnace temp. is attained is large, the time therefor is short with a less delay in the initiation of the A1 transformation and the so-called heating delay is small. For the case of (c), the situation is reverse to the case (a). These relations are expressed by the equations and the carburization area of the object to be treated can be counted back from the change at the above-mentioned respective points. The actual treatment condition and the actual condition of the object to be treated are thus known and the effective controlled atmosphere treatment is made possible.
