Inventor: KUME MASAHIRO
IPC: H01S5/22
Filed: 1991-12-12
Abstract: PURPOSE:To obtain phase-locked oscillation of high output wherein the conver sion efficiency from current to light is high, and the phase of each laser light between arrays is synchronized, by making the AlAs mixed crystal ratio and the forbidden bandwidth of a current block layer larger than those of a clad layer, and reducing the refractive index. CONSTITUTION:On an N-type GaAs substrate 1, a buffer layer 2 composed of N-type GaAs is formed, on which the following are formed; a first clad layer 3 composed of Ga0.5Al0.5As, an active layer 4 composed of Ga0.85Al0.15As a second clad layer 5 composed of P-type Ga0.85Al0.15As, and a third clad layer 6. For current constriction, a current block layer 7 composed of N-type Ga0.4Al0.6 As is formed except the region turning to a current channel 11. The refractive index of the current block layer 7 is smaller than that of the second clad layer 5 in a current channel 11, and laser light is confined in the current channel 11 by the effect of refrax index difference.

Filed: 1988-12-26
Abstract: PURPOSE:To perform an extraction by a simple operation while preserving triple bonds by employing supercritical carbon dioxide as an extraction solvent when polyacetylene compounds having a plurality of carbon triple bonds in their structures are extracted from a plant. CONSTITUTION:When compounds of formulas I, II, etc., contained in the roots and stem of Atractylodes japonica Koidzumi are extracted therefrom, the extraction is performed with supercritical carbon dioxide at 35-60 deg.C under 100-300kg/ cm<2>G to improve the yield of the extraction.
