Abstract : The instant invention overcomes the problems encountered in the past by providing an incident radiation absorber which is capable of being easily incorporated within an already existing laser. In a typical conventional cylindrical chemical laser supporting structures such as struts which in many instances carry radial feed passages therein, are attached at one end to the center body of the laser and at the other end to the surrounding laser support structure. The incident radiation absorber of this invention is positioned within the support structure of the laser surrounding the laser center body and is designed to absorb the incident radiation from, for example, the supporting struts. By the addition of the absorber of this invention within an already existing laser damage to the laser is substantially eliminated without introducing additional stray beams of radiation that would additionally cause parasitic losses within the laser. Furthermore, a reflective element may be utilized in conjunction with the absorber of this invention in order to provide better redistribution of the incident reflection.
