As of July 2011 three people had been charged under the federal Aeronautics Act, which carries a maximum penalty of $100,000 and five years in prison, for attempting to dazzle a pilot with a laser. Other charges that could be laid include mischief and assault. The "RESOLUCIÓN 57151 DE 2016" prohibits the marketing and making available to consumers of laser pointers with output power equal to or greater than one milliwatt (>=1 mW). Colombia is the first country in South America to regulate the marketing of these products. UK and most of Europe are now harmonized on Class 2 (<1 mW) for General presentation use laser pointers or laser pens. Anything above 1 mW is illegal for sale in the UK (import is unrestricted). Health and Safety regulation insists on use of Class 2 anywhere the public can come in contact with indoor laser light, and the DTI have urged Trading Standards authorities to use their existing powers under the General Product Safety Regulations 2005 to remove lasers above class 2 from the general market. A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot. The beam may be focused with lenses. The report says that the incident was investigated by several independent authorities, including the Belgian police, and that those authorities concluded that pointers brought in by the audience were the cause of the injuries. Laser pointers can be used in hiking or outdoor activities. It can be used as a rescue signal in emergencies which is visible to aircraft and other parties, during both day and night conditions, at extreme distances. For example, during the night in August 2010 two men and a boy were rescued from marshland after their red laser pen was spotted by rescue teams. In addition to the safety hazards of unfiltered IR from DPSS lasers, the IR component may be inclusive of total output figures in some laser pointers. Though green (532 nm) lasers are most common, IR filtering problems may also exist in other DPSS lasers, such as DPSS red (671 nm), yellow (589 nm) and blue (473 nm) lasers. These DPSS laser wavelengths are usually more exotic, more expensive, and generally manufactured with higher quality components, including filters, unless they are put into laser pointer style pocket-pen packages.

Definition: devices used for pointing at items with laser beams Green laser pointers are often based on a miniature Nd:YVO4 laser with a KTP crystal for intracavity frequency doubling. Here, Nd:YVO4 is beneficial for a low threshold pump power, and KTP works in a relatively wide temperature range, thus not requiring means for temperature stabilization. Lay persons often ask what is the range of a laser pointer, and responding to this interest some producers specify some questionable numbers. If the question is meant to be how far the light of a laser pointer can propagate, the correct answer is that there is no limit, provided that the light is not absorbed or scattered away in the atmosphere.

Laser pointers (sometimes known as laser pens) are compact, handheld laser devices. They are typically used to highlight an object or point of interest by illuminating it with a bright spot of colored light. To address the concerns above, the Center for Devices and Radiological Health (CDRH) — a division of the US Food and Drug Administration (FDA) — maintains a laser safety classification scheme based on six product classes. Internationally, lasers are specified by different classes described in the IEC 60825 standard. As shown in the Lasers Specification Guide, all lasers consist of three components: an energy source (also known as a pump), a laser (or gain) medium, and an optical resonator; these components are shown in the image below. Essentially, the pump provides energy which is amplified by the gain medium. This energy is converted into light and is reflected through the optical resonator which then emits the final output beam. ... While early laser pointers were pumped by helium-neon (HeNe) gas, nearly all modern laser pointers use electrically-powered laser diodes as their energy source. While all lasers are capable of emitting visible as well as ultraviolet and infrared light, laser pointers are typically confined to the visible spectrum due to the inherent need for a viewer to see its output.
