how to make a red laser pointer burn

A man was chased down by officers after pointing the Laser Pointer3000mw beam from his pellet gun at a police helicopter.The Air2 police helicopter was responding to an emergency call when the bright light source was shone directly at the pilot and tactical flight officer while they were in the air.
In the clip, the pilot is seen locating the source of the 5 in 1 Laser Pointer beam on his infrared camera before directing officers towards the suspect's location.Realising he is being tracked, the man immediately attempts to run, throwing the gun onto the ground as he disappears into a cluster of trees.
Officers on the ground later in Vaughan, Canada, managed to locate the handgun, which turned out to be a pellet gun with a Blue Laser Pen scope mounted on it, according to police reports.
Laser pointers, whilst a useful training tool, can present a hazard that is capable of causing harm to eyes. It is difficult for many people to believe that a device that looks like an ordinary penlight and runs on AAA batteries can be dangerous. However, within each pointer is a small yet powerful Red Laser Pen Pointer diode. Laser pointers have recently become relatively common and have unfortunately been misused on humans. An incident in 1999 in Western Australia resulted in permanent eye damage to a 12 year old boy.

Laser classification gives an indication to their degree of hazard:
Class 1 and 1M lasers are safe for normal viewing under reasonably foreseeable conditions
Class 2 and 2M lasers would not cause permanent eye damage under reasonably foreseeable conditions. Damage is usually avoided by your blink reflex or aversion response
Class 3R lasers (previously called class 3A) have the potential to cause eye injury, especially in the hands of an unaware, untrained, or careless operator. The resultant injury can range from temporary flash blinding (similar to a visual after image) to a slight retinal lesion
Class 3B lasers can cause eye injury but will not generally damage the skin
Class 4 lasers are extremely hazardous to the eye and skin (either directly or by a reflection).
