金属表面附近光学薄增益介质中的激光与无反转激光

Lasing versus lasing without inversion in an optically thin gain medium near a metal surface

V. G. Bordo

摘要:

从第一性原理出发,发展了金属表面活性中心光学薄层中的激光理论。该方法是基于一个严格的帐户在附近的反射表面,它提供了一个反馈偶极子振荡的活动中心的本地字段。结果表明,增益介质的厚度在激光条件中起着至关重要的作用,并控制着从常规激光到无反转激光的切换。进行了数值计算的掺铒玻璃接壤的黄金表面,在电信波长(1532 nm)的辐射可以产生。

英文摘要:

A theory of lasing in an optically thin layer of active centers disposed at a metal surface is developed from first principles. The approach is based on a rigorous account of the local field in a close vicinity of a reflective surface which provides a feedback for dipole oscillations in active centers. It is demonstrated that the gain medium thickness plays a crucial role in the lasing condition and controls a switching from conventional lasing to lasing without inversion. The numerical calculations are carried out for erbium doped glass bordering a gold surface where radiation at telecom wavelength (1532 nm) can be generated.
