Pengukuran Panjang Koherensi Menggunakan Interferometer Michelson
Abstract: A simple measurement
of coherence length of He-Ne laser, red diode laser, and green diode laser
using Michelson interferometer has been conducted. The steps in this research
were setting up the Interferometer by places movable mirror on mirror rail. To
determine the coherence length of the laser’s light, movable mirror has been
shifted until the interference fringes disappear on the screen. Results of
measurement for the coherence length of He-Ne laser I is cm, He-Ne laser II is cm, red diode laser I is cm, and green diode
laser II is cm.
