摘　　要：研制了包括泵浦源在内的一体化小型腔式光泵ＮＨ３远红外激光器，实验测量了输出功率、工作气体压强、腔体长度与腔体耦合条件之间的优化规律：发现了小型腔式光泵远红外激光器中普遍存在的特别宽带的激光辐射现象，这将是解决远红外激光频率大范围连续可调谐的一个新途径．A unified miniature optically pumped NH 3 FIR laser (unified mini OPFIR cavity laser),including a mini TEA CO 2 pump laser, was developed. The optimum operation of the unified mini-OPFIR cavity laser was studied experimentally. The relations among FIR laser output power, operating gas pressure, length and coupling condition of the cavity were measured. lt was found that the very wide band FIR laser emission was a common feature of the mini OPFIR cavity laser. This will be a new way for wide range frequency tuning of FIR laser.
