Common Components of all Lasers ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Laser Components Gas lasers consist of a gas filled tube placed in the laser cavity. A voltage (the external pump source) is applied to the tube to excite the atoms in the gas to a population inversion. The light emitted from this type of laser is normally continuous wave (CW).

Laser Output watt (W) -  Unit of power or radiant flux (1 watt = 1 joule per second). Joule (J) -  A unit of energy  Energy (Q) The capacity for doing work. Energy content is commonly used to characterize the output from pulsed lasers and is generally expressed in Joules (J). Irradiance (E) -  Power per unit area, expressed in watts per square centimeter. Time Continuous Output (CW) Pulsed Output (P)                         Energy (Watts) Time Energy (Joules)

Common Laser Signs and Labels
CONCLUSION: Laser communication in space has long been a goal for NASA because it would enable data transmission rates that are 10 to 1,000 times higher than traditional radio waves. While lasers and radio transmissions both travel at light-speed, lasers can pack more data. It's similar to moving from a dial-up Internet connection to broadband. Astronomers could use lasers like very accurate rulers to measure the movement of planets with unprecedented precision. With microwaves, we're limited to numbers like a meter or two in distance, whereas [lasers have] a potential for getting down into well beyond the centimeter range.
