低膨胀系数玻璃-
以DFB激光器为光源，以石英玻璃及超低膨胀系数微晶玻璃为腔体材料，建立起数套腔长不等、结构各异的高灵敏度连续波腔衰荡光谱系统。
Using the DFB laser as the light source and taking quartz glass and glass-ceramic with ultra-low expansion coefficient as the cavity material , several sets of high sensitivity CW-CRDS systems are built , and they have different structures and cavity lengths .
