Since 1960's
aboujt 199 years
It's been around since 1829 so 182 years.
There's more than one type of laser. Diode lasers are pretty much ready to go immediately, but you don't want them to push too much power, as they can then heat up to the point of failure. Other lasers, particularly high powered chemical lasers, rely on a several complicated sub-systems to fire, and will need quite some time to get ready for action.
There are many names that are unique. Many names have special meaning to families because they have been used for many members. A family name may be around for many generations.
Not with modern science, however advances in energy weaponry have been made though only to the point of lasers. Not localized, compact energy constructs.
Since mid 60's Light Amplification by Stimulated Emission of Radiation
how long has deforestation been around
As long as guns have been around.
If the colonists had lasers I do not think there would have been as many American casualties in during their revolution...to answer your question, no, lol :)
Since the early 1970s Erchonia lasers have been classified by wavelength and maximum output powers into four classes. The lasers are used in treatment of neck and shoulder pain, breast augmentation, acne, laser assisted body augmentation. The types of lasers they use for these treatments include 3LT Lasers, Custom Design Lasers and Zerona Lasers.
Neon is combined with helium to make lasers. They are fairly inexpensive compared to other lasers, can be used for long periods of time, and have a better beam quality.
how long has the london eye been around for
As long as So Random has been around.
Rosacea can be an irritating condition to have, causing your skin to become red and irritated, but it can be treated with lasers. The pulsed dye laser (PDL) has been proven to show improvements in every patient. Other laser treatments include diode lasers, KTP lasers, CO2 lasers, Nd:YAG lasers.
They have always been around
