低阈 meaning in English
low threshold
Examples
- Theyb : gso laser obtained a lowhreshold of 77mw which is the lowest threshold in the world as far as we know
Yb : gso获得了77mw的低阈值，据我们所知，这是目前世界上yb : gso激光器中阈值最低的纪录。 - There are many optical depletion mechanisms , such as diffraction depletion , the transimission of a reflector , scattering of the medium in the cavity , non - life absorption and so on , so the quality factor ( q factor ) is low . in
利用这种微谐振腔制作的激光器,其自发辐射频率落在光子晶体的禁带范围内,有效降低了激光振荡的阈值,从而使激光器具有低阈值高效的特点。 - There are many approaches to achieve the purpose , and one of the perfect them is tunnel - cascaded multi - active regions large cavity ld structure , in which not only the effective thickness of the active region increase but also obtain lds ’ low threshold current and high slope efficiency and other properties
有多种途径实现ld光束特性的改善,其中采用多有源区隧道结级联大光腔结构的半导体激光器是既增加有源区等效厚度而又保证ld低阈值电流和高斜率效率等特性的最佳途径之一。 - Based on the above , we have made a research on the fabrication technology of two - dimensionally ( 2d ) arrayed surface - emiting lasers , and have obtained two - dimensionally arrayed laser primarily with lower threshold current density and higher power output , which will promote the achievement of higher reliability , lower threshold current arrayed surface - emiting lasers laser for high power output
在此基础上进行了面发射半导体激光器二维( 2d )列阵的制备研究，初步获得了具有较低阈值电流密度和较高功率的45偏转镜面发射阵列半导体激光器，为研制高可靠性、高功率、低阈值电流的面发射阵列半导体激光器奠定了一定的基础。
