A simultaneous dual-wavelength continuous wave, quasi-cw or linearly polarized wave diode-end-pumped Nd:YAG laser operating at 1319nm and 1338nm is demonstrated. To the best of our knowledge, our experimental results achieve the highest level in the domestic domain. The simultaneous dual-wavelength laser provides an experimental basis for generating highly coherent THz wave radiation of 3.23THz by nonlinear optical difference frequency method.2. A diode-end-pumped Nd:YAG crystal, type-I critical phase matching LBO crystal intra-cavity frequency doubled, simultaneous multi-wavelength red laser at 659.5nm, 664nm and 669nm is firstly realized.

In small intestine, AKP activity was mainly distributed over four areas of epithelial cells: cytomembrane, cytoplasm, microvillus and the carbohydrate-riched cell coat. In liver, it was mainly located in canaliculi. In kidney, it mainly existed in such zones as brush border and memebrane of epithelial cells of proximal tubule, and cracks between kinds of tubules.

The DLC film deposited at substrate temperature of 100℃ shows the best integrated property with carbon content of sp〓 bonding state up to 40% which is two times more than that in the films prepared by Americans with the same method. Accordingly, the microhardness is up to 30Gpa, and friction coefficient and optical band gap decrease to 0.10 and 1. 76eV respectively. It is found that sp〓C content in DLC films decreases with the increasing substrate temperature in the process of film deposition, especially after 300℃.
