The conditions for obtaining white laser light were studied. Further, it was discovered that the absorption of helium by cadmium during condensation seriously affected the life of such a laser.

研究了获得白激光的条件，井发现镉冷凝时吸氦严重影响激光管寿命。

With these equations we have designed for helium-cadmium lasers a new type of helium replenisher, which has lengthened the life time of a He-Cd laser to over 1000 hours so far.

按此方程所设计的用于长寿命氦—镉激光器的新型氦补充器，使氦—镉激光器寿命已超过一千小时。
