The research of long wavelength semiconductor saturable absorption and it s application in passive modelocking and Q-switching of the solid-state lasers;

We demonstrate a tunable long wavelength photodetector which is fabricated by bonding a GaAs-based filter with a InP-based p-i-n detector.

High speed and long wavelength photodetector is the key device for high bit rate optical fiber communication systems and optical networks that need wide frequency bandwidth and high external quantum efficiency simultaneously.

Based on the CJ267-91,the text studies the effect of solvent,the preparation of the normative sample and the wave-length upon the result of mensurating mineral oils, so that it′s possible to choose the suitable condition to improve the accuracy of the mensurating results.
