Abstract

It is desirable to employ lasers in such a manner that they are mutually quenching. That is, the output of a first laser is employed to quench the lasing action of a second laser. Moreover, the output of the second laser can be employed to quench the lasing action of the first laser. The energy extracted from a quenched laser is a function of the length of travel of the quenching beam through the quenched laser. Thus, it is desirable to have a short path for the lasing mode of the quenching laser and a long path for the quenched laser. Such related lasers can be employed as a bistable trigger device, as shown.

Use of Active Filaments in Improving the Quenching Action and Bistable Operation of Injection Lasers

It is desirable to employ lasers in such a manner that they are mutually quenching. That is, the output of a first laser is employed to quench the lasing action of a second laser. Moreover, the output of the second laser can be employed to quench the lasing action of the first laser. The energy extracted from a quenched laser is a function of the length of travel of the quenching beam through the quenched laser. Thus, it is desirable to have a short path for the lasing mode of the quenching laser and a long path for the quenched laser. Such related lasers can be employed as a bistable trigger device, as shown.

Element 2 is an injection lasher having highly reflective backing 4 located in the direction of the lasing mode of injection laser 2. A second laser 6, which is to serve as the quenched laser, is disposed in the path of laser 2. Thus, the light output of laser 2 travels through a relatively long path of laser 4. A second highly reflective backing 8 is placed adjacent laser 6 so that such backing reflects the right produced by injection laser 6 towards mirror 10. This reflects the light emanating from laser 6 towards mirror 12 which in turn traverses the

The arrangement permits a short path for the lasing mode of quenching laser 2 and a long path for such mode through quenched laser 6. Reflectors 4 and 8 serve to enhance the strength of the lasing modes of th...
