Title: Semiconductor laser
Inventor: TSUNEKAWA YOSHIFUMI
IPC: H01S5/00
Filed: 1987-08-19
Abstract: PURPOSE:To allow the control of oscillation of only fundamental transverse mode oscillation while maintaining longitudinal multimode, keep oscillation threshold value to be low, and then allow for a stable oscillation up to a high output by specifying the angle between a rib-like side face of an optical waveguide path and junction plane. CONSTITUTION:In a semiconductor laser where a rib-like photoconductive wave path is provided and ZnSe layer 209 which is the II-IV compound semiconductor layer is embedded into the photoconductive wave path side face, an angle thetabetween the rib-like optical waveguide path side face and junction plane is allowed to be 50 or 120 degrees. If the angle is less than 50 degrees, the threshold current increases and the maximum light output decreases. If it exceeds 120 degrees, a high-order oscillation is seen in transverse mode. Only the fundamental transverse mode oscillates at a low threshold current while maintaining longitudinal multimode oscillation and a high-output laser oscillation with small astigmatism is enabled.

Filed: 1987-08-19
Abstract: PURPOSE:To obtain an evaluating apparatus, which can examine a globe sensor simply, by providing an electric control means of a shutter, which can set the intermittent time width of infrared rays and the repeating period of the time width arbitrarily. CONSTITUTION:A period counter 5 counts clock pulses (k). Every time the number of the pulses corresponding to the period for the counted value is counted, a pulse signal (a) having the width of the pulse corresponding to the period is generated. The signal (a) is added to a code width counter 6. The pulses (k) are further added. Until the time the specified number of the pulses (k) is counted from the rise-up time of the pulse, a pulse signal (b) having the width of the pulse corresponding to the period is generated. When, the signal (b) is applied to a shutter driver 3, an electromagnetic shutter 2 is opened during the time corresponding to the width of a globe code. The shutter 2 is closed for the other time. Therefore, infrared rays at a black body plate 1 can be made to be intermittently lighted and inputted into the globe sensor. When the counted values of the counters 5 and 6 are changed, the repeating period and the width of the intermittent time of the infrared rays can be change.
