Using internal mirrors inside tube,mirror get eroded by gas discharge Ang need to be replace .the resonator mirror external to laser cavity create great flexibility but when it used the ends of discharge tube cause a loss due to reflection
The Death Star uses a laser to destroy Alderaan.
It was called "The Mirror of Erised". The Mirror of Erised if I remember correctly

This is essentially correct. A beam of light, when striking the plane of a mirror, will be reflected from that surface at the same angle as the incident beam.

"The laser beam is initiated and directed toward the octagonal mirror called the scanning mirror." (pg. 1134, Chapter 21, A+ Guide to Managing and Maintaining Your PC)
The most common method is through the use of a beam splitter. This employs -- to keep it simple -- a partially transparent mirror placed at a 45 degree angle relative to the laser beam. Some of the beam passes through the mirror, and the rest is reflected perpendicular to the original beam by the mirror.
Yes. The moon's high albedo is used as a mirror to reflect laser light from the Earth. They more accurately track the orbit and distance of the moon than previous methods. However, in order to have a reflected laser beam that the eye could see (like in a movie) the laser would have to be incredibly strong and have a large beam. No laser currently on Earth is capable of this. However, the moon's albedo is high enough that if such a significantly large laser existed it could reach the moon and be reflected back.
Back up the indecent beam path.

A mirror is aligned on a laser tube using an apparatus comprising a window spaced from the mirror and a means for containing fluid, such as a bellows, between the window and the mirror. The window and the fluid have an index of refraction that matches that of the mirror. The bellows permits the mirror's relation to the window to be changed without the loss of the fluid. In aligning the lasing mirror, the window is oriented normal to a light beam from an autocollimator. The mirror is then placed in contact with the laser tube and oriented so that the beam from the autocollimator is reflected back on itself.
