If I were designing this thing, the solid state LASER would be isolated from the cylinder by a quartz or sapphire (or similar) window. If the article identified the LASER wavelength, I could suggest reasonable window materials.

Now that you mention it I recall an article I read years ago about the engine development lab at Ford using a quartz or sapphire window in an experimental engine so that they could film the combustion wave while the engine was running.
Of course the same question arises how long the crystal window will last. With an experimental engine the cost of replacing the window is unimportant. The cost of replacing one in your daily driver is a different matter.

Good call.
The design in question does use a window to isolate the laser from the inhospitable cylinder..
