Optical amplifier
An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal. An optical amplifier may be thought of as a laser without an optical cavity, or one in which feedback from the cavity is suppressed. Optical amplifiers are important in optical communication and laser physics.
There are several different physical mechanisms that can be used to amplify a light signal, which correspond to the major types of optical amplifiers. In doped fibre amplifiers and bulk lasers, stimulated emission in the amplifier's gain medium causes amplification of incoming light. In semiconductor optical amplifiers (SOAs), electron-hole recombination occurs. In Raman amplifiers, Raman scattering of incoming light with phonons in the lattice of the gain medium produces photons coherent with the incoming photons. Parametric amplifiers use parametric amplification.
Laser amplifiers
Almost any laser active gain medium can be pumped to produce gain for light at the wavelength of a laser made with the same material as its gain medium. Such amplifiers are commonly used to produce high power laser systems. Special types such as regenerative amplifiers and chirped-pulse amplifiers are used to amplify ultrashort pulses.

Girl Ridin' Shotgun
by: Joe DiffieWhoa, she's a hot one
It's a hot day, and I've got a pocketful of money
Friday, tires roarin', you can hear me comin'
Cooler in the back, Bud Light ice cold
Me and my buddies cuttin' down an old back road
I got a jacked up truck, but it ain't much
A fixer upper with a brand new clutch
Yeah, it takes me anywhere I wanna go even though
It's hard for me to keep my eyes on the road
But that girl ridin' in the shotgun
Sunkissed by the Dixie hot sun
Whoa, she's a hot one, yeah
Aldean all up on the radio
Dashboard lights shinin' on my baby, oh
Later on, gonna have me a little fun
With that girl ridin' shotgun, yeah
Whoa, girl ridin' shotgun
She's the girl of my dreams, she gives me everything
Wearin' short shorts or some tight blue jeans
She's country, and she ain't afraid to break a nail
Raise hell, or go to jail, I keep her by my side
She's always ready to ride, and sometimes
She even drives when it's in four wheel drive
Never known to back down from anything
And you know she keeps her motor clean, yeah
That girl ridin' shotgun
Sunkissed by the Dixie hot sun
Whoa, she's a hot one, yeah
Aldean all up on the radio
Dashboard lights shinin' on my baby, oh
Later on, gonna have me a little fun
With that girl ridin' shotgun, yeah
Whoa, girl ridin' shotgun
She could be the centerfold of "Field and Stream"
Holdin' that double barrel twelve gauge
To me, nothin' sweeter than a Georgia peach
Playin' air guitar to a song I sang, a song I sang
Talkin' 'bout
That pretty little redneck girl ridin' shotgun
Sunkissed by the Dixie hot sun
Whoa, she's a hot one, yeah
Aldean all up on the radio
Dashboard lights shinin' on my baby, oh
Later on, gonna have me a little fun
With that girl ridin' shotgun, yeah
Whoa, girl ridin' shotgun
