查询词典 quasi coherent

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.

本论文主要围绕用于差频产生THz辐射源的多波长激光器及THz光子晶体的带隙特性分析而展开，论文的主要内容包括：一、从LD端面泵浦固体激光器的激光阈值公式出发，理论计算了腔镜对于两个波长的透过率关系，实现了LD端面泵浦Nd：YAG 1319nm/1338nm双波长激光连续、准连续及线偏振稳定输出。

Two recent experimental breakthroughs in the field of atomic physics are reported:the realization of a well-collimated,widely tunable,quasi-continuous wave atom laser,and the generation of matter waves via coherent multi-wave mixing.
