Having worked for a laser manufacturer I am familiar with the wavelength and characteristics of diode lasers but only passingly familiar with plasma twisting technology. However it seems to me that whether the laser pointer affects the plasma or not (I would guess that it would have no effect, the only danger with plasma is undervoltage conditions or burn in from static images) it is an unsafe practice to shine a red diode at a reflective surface. You risk severe eye damage or even blindness. I believe that there are LED light dot pointers (in various colors) available at low cost that would serve as a safe pointer.

What do you mean by : ".....undervoltage conditions or burn in from static images.."

Do you mean that if I PAUSE/STILL an picture from a DVD on from the TV itself then there is a danger to the plasma ?

"it is an unsafe practice to shine a red diode at a reflective surface. You risk severe eye damage or even blindness" Point taken.

I believe that there are LED light dot pointers (in various colors) available at low cost that would serve as a safe pointer" ...Are you saying these LED pointers are safe not only for the Plasma but also for the Eyes from reflection/direct. Your further advice please .

My Laser pointer specification : Laser Diode , Wavelength 635-680 nm, Maximum Outpur lexx than 3mW , Class 2 Laser product. --What do these all mean if you care to clarify for the benefit of the uninitiated.

Thank you very much.

  A laser emits coherent light. The "waves" are synchronized.
  
  LEDs (ordinary, not laser) emit incoherent light, like a flashlight with an incandescent bulb.
