A flat high efficiency super-broadband source was presented. We achieved a C+L-band superfluorescent source, in the region from 1524. 0 to 1600.4nm, the power of the ASE are over -12. 0dBm and the ASE profile excursion is only ±1. 4dB in the region from 1539. 2 to 1600.4nm. The power of the ASE is 22. 1mW and the power conversion efficiency is 18. 8%. 9. The amplification characteristics of thulium-doped fiber amplifier had been studied using the basic theory for fiber amplifier. The connection between the Tm-doped fluoride fiber and silicon fiber was accomplished, and we studied the TDFA and the reason that the expecting results hadn't achieved had been analyzed. The assumption of the Er-Tm-co-doped silicon fiber had been presented, and we studied the Er-Tm-co-doped silicon in cooperation with the correlative corporation, some results had been got and the further studies are carried on.

The experimental results show that: DNA of normal gastric mucosa has stable phosphate backbone; Since the peak intensity at 1090 cm^(-1) is lower than that at 1050 cm^(-1), phosphate backbone in DNA of intestinal metaplasia becomes unstable, while the rest spectra peaks are similar to those in normal gastric mucosa; In terms of adenocarcinoma DNA, double peaks at 1090 cm^(-1) whose intensity are higher than 1050 cm^(-1), are observed, which indicates that DNA chain is broken and re-forms a double stabilized phosphate backbones. In addition, peaks at 950 cm^(-1), 1010 cm^(-1), 1100~1600 cm^(-1) also exhibit obvious difference compared with normal gastric mucosa, which shows that deoxyribose and bases are changed due to broken of DNA.

实验结果表明，胃粘膜正常组织DNA中有稳定的磷酸骨架；肠化组织基因组DNA拉曼特征峰在1090 cm^(-1)处谱峰强度低于1050 cm^(-1)处谱峰强度，表明其磷酸骨架变得不稳定，其它位置的谱峰与正常组织相似；腺癌组织基因组DNA拉曼特征峰在1090 cm^(-1)附近出现双峰，其相对于1050 cm^(-1)处谱峰强度更强，提示DNA有可能出现断链并再次形成了稳定的磷酸骨架，在950 cm^(-1)、1010 cm^(-1)、1100~1600 cm^(-1)波段的特征谱峰与正常组织DNA相比变化也较大，说明脱氧核糖和碱基可能由于DNA断链也随之改变。
