Laser pointers are often used in educational and business [[presentation]]s and visual demonstrations as an eye-catching pointing device. Laser pointers enhance verbal guidance given to students during surgery. The suggested mechanism of explanation is that the technology enables more precise guidance of location and identification of anatomic structures.<ref>{{cite journal |last1=Badman |first1=Märit |last2=Höglund |first2=Katja |last3=Höglund |first3=Odd V. |title=Student Perceptions of the Use of a Laser Pointer for Intra-Operative Guidance in Feline Castration |journal=[[Journal of Veterinary Medical Education]] |volume=43 |issue=2 |pages=1–3 |doi=10.3138/jvme.0515-084r2 |pmid=27128854 |year=2016 |doi-access=free }}</ref>

Red laser pointers can be used in almost any indoor or low-light situation where pointing out details by hand may be inconvenient, such as in [[construction]] work or interior decorating. Green laser pointers can be used for similar purposes as well as outdoors in daylight or for longer distances.

Laser pointers are used in a wide range of applications. Green laser pointers can also be used for [[amateur astronomy]].<ref>{{cite journal |last1=Bará |first1=S |last2=Robles |first2=M |last3=Tejelo |first3=I |last4=Marzoa |first4=RI |last5=González |first5=H |title=Green laser pointers for visual astronomy: how much power is enough? |journal=[[Optometry and Vision Science]] |volume=87 |issue=2 |pages=140–4 |doi=10.1097/OPX.0b013e3181cc8d8f  |pmid=20035242|year=2010 |s2cid=5614966 }}</ref> Green lasers are visible at night due to [[Rayleigh scattering]] and airborne dust,<ref>{{cite book |last1=Metzger |first1=Robert M. |title=The Physical Chemist's Toolbox |date=2012 |publisher=John Wiley & Sons |isbn=978-0-470-88925-1 |page=207 |url=https://books.google.com/books?id=vhump_5PsaoC&q=green+laser+rayleigh+scattering&pg=PA207 |access-date=15 June 2016}}</ref> allowing someone to point out individual stars to others nearby. Also, these green laser pointers are commonly used by astronomers worldwide at [[Star party|star parties]] or for conducting lectures in astronomy. Astronomy laser pointers are also commonly mounted on telescopes in order to align the telescope to a specific star or location. Laser alignment is much easier than aligning through using the eyepiece.
