Anti-laser aerosol

Anti-Laser Aerosol was in use by the Federation.

This aerosol is contained in a 10 by 30 centimeter cylinder. When activated, the cylinder releases a thick, reddish smoke that partially deflects and absorbs laser and phaser fire, as well as obscuring vision. The effect lasts for several seconds to several minutes, depending on atmospheric conditions (a strong wind or starship air-recycling system greatly lessens the aerosol's effectiveness). Each cylinder contains one application. (FASA RPG module: Star Fleet Intelligence Manual: Agent's Orientation Sourcebook)
