Discussion Overview

The discussion centers around the use of laser technology in military contexts, particularly in Iraq and Afghanistan. Participants explore the effectiveness, applications, and implications of high-powered laser pointers as non-lethal deterrents in combat situations.

Discussion Character

  • Debate/contested, Technical explanation, Conceptual clarification

Main Points Raised

  • Some participants note that laser diodes, commonly found in consumer electronics, have been repurposed for military use in conflict zones.
  • One participant questions the effectiveness of high-powered laser pointers, arguing that even a 500mW laser is not lethal and primarily serves as a scare tactic.
  • Another participant emphasizes that while high-powered lasers can cause temporary blindness, they do not pose a significant threat to life, suggesting that other deterrents like tasers or pepper spray are more effective.
  • There is a mention of the historical use of laser pointers in military operations dating back to the Vietnam War, indicating a long-standing application of this technology.
  • One participant expresses confusion over the inclusion of Liverpool in the discussion, questioning its relevance to the topic.

Areas of Agreement / Disagreement

Participants exhibit disagreement regarding the effectiveness and implications of using high-powered laser pointers in military settings. There is no consensus on their utility as a deterrent or their potential risks.

Contextual Notes

Some claims about the effectiveness and safety of laser pointers depend on specific conditions, such as the quality of the laser and the context in which it is used. The discussion does not resolve these uncertainties.

Lasers in combat? That used to happen only in "star wars" but not any more.

That cute essential little laser diode in your DVD drive/printer/PS3 etc has been put to more dynamic uses. Such as being used in trouble spots such as Iraq, Afghanistan and Liverpool.

This article gives full details on their use.

Weird article. What does this bit mean?

These high powered laser pointers are commercially available and are normally purchased by military personnel and their families online. In situations when lives are at stake, it is essential for the laser pointer to be effective. An effective laser pointer should be high power (at least 75mW), high quality components and have out standing beam specifications. Lives could easily be lost if poor quality, low power shoddy laser pointers were used.

What? Even a 500mW laser is not going to kill anyone (it can certainly blind someone easily). These lasers are mainly going to be used for scare tactics, working only on the ignorant or unsophisticated. So what difference will it make if the laser if 5mW or 500mW? Even a 5mW beam is seen well in the dark of night (via Rayleigh scattering).

Even the operator's life is not in any danger from a poorly constructed laser with a divergent beam and significant IR-leak through (from the pump laser). Eyesight might certainly be at risk, but not life.

BTW, I have personal experience with these "pointers", having recently got a 200mW ClassIIIb 532 nm (green) one. It can burn garbage bags and electrical tape and can singe skin within a couple of seconds, but it's hardly a serious deterrent. The only way it can help in a crunch is if I use it to dazzle an opponent or assailant with a direct hit to an eye (which will also leave him with retinal damage).

A taser or even a can of pepper spray would make for a better deterrent.

Liverpool? :bugeye:
