Recently as a new harvest of the bandgap engineering of the semiconductor, OPS-VECSEL is a promising candidate of a high quality laser in science research and industry process.
Compared OPS-VECSEL to solid-state lasers,the new type of laser may provide significantly increased wavelength variability by material selection and bandgap engineering of the semiconductor.
By building up the material storage and setting optical power density, center wavelength, threshold, scan step size and calculation precision, the output characteristics of these devices were calculated.

Study on microwave combined with granular active carbon for treatment of p-nitrophenol wastewater Yuan Dong a, Fu Dayoub, Luo Zhiwen c College of Material and Chemical Engineering Department, Sichuan University of Sciences and Engineering , Zigong 643000, China aemail:yuandong68@126.com, bemail:fdy888@263.com, cemail: luoyanlizw@sina.com Keywords: p-nitrophenol wastewater; Microwave; activated charcoal Abstract: A microwave technique assisted with granular active carbon(GAC) was used for the degradation of p-nitrophenol(PNP) wastewater.
Microwave (MW) is an energy composed of an electric field and magnetic field, which frequency range from 300 MHz to300GHz and can provide rapid heating of materials.
GAC is an excellent MW absorbing material to convert MW energy into thermal energy [12].
