氧碘混合过程是化学氧碘激光器(COIL)中的一个重要步骤,氧碘混合质量直接决定着COIL的运行效率和光束质量。采用化学荧光法,研究了两种不同结构的扰动翼片组对COIL超音速平行流混合过程的影响。实验结果表明,1#扰动翼片组对氧碘超音速平行流的混合增强效果明显,其荧光区达到主气流中心线所经历的流向距离大幅缩短,碘解离区内的荧光区与测试区的面积比相对于无混合扰动时提高了4.2倍;采用2#翼片组扰动混合时,流向距离值进一步缩短了40%~60%,碘解离区内的面积比值又提高了20%~40%。氧发生器有/无主载气条件(2#翼片组)下的混合过程比较显示后者混合效果更好。 相似文献

Results of an experimental investigation of a chemical oxygen-iodine laser (COIL) are presented. We determine the factors
influencing the efficiency of a chemical singlet-oxygen generator (SOG) of the bubbler type operating on the chlorination
of an alkaline solution of oxygen peroxide. We describe SOG constructions. A cw COIL with output power up to 400 W is developed
on the basis of the investigated SOG. The feasibility of a modular construction of high-power COIL is demonstrated. A power-output
level of 1 kW was achieved with a two-section laser. The feasibility is analyzed of COIL operation in a pulsed regime by pulsed
bulk accrual of iodine atoms. We show that in this regime the laser can be operated without a low-temperature trap. An advantage
of such a regime is also the possibility of controlling, in a wide range, the lasing pulse duration. A strong influence of
molecular chlorine on the energy content of the active medium is observed when alkyliodides are used as iodine donors. The
possibilities of using a pulsed COIL for controlled thermonuclear fusion are discussed.
