五态介质中双味涡旋原子Laser的产生
Generation of Two-Flavor Vortex Atom Laser from a Five-State Medium
摘要:
利用电磁感应透明(EIT)技术,在$M$型五能级系统中,利用两束分别具有$\pm z$ -方向轨道角动量$\pm l\hbar$的探测光,获得并分析了涡旋态双味原子激光.结合原有的量子态从光波到物质波的转移技术,本文的结果可以推广到用非经典原子产生连续双味涡旋原子激光。
英文摘要:
Two-flavor atom laser in a vortex state is obtained and analyzed via electromagnetically induced transparency (EIT) technique in a five-level $M$ type system by using two probe lights with $\pm z$-directional orbital angular momentum $\pm l\hbar$, respectively. Together with the original transfer technique of quantum states from light to matter waves, the present result can be extended to generate continuous two-flavor vortex atom laser with non-classical atoms.
