DIODE LASER FREQUENCY STANDARD FOR LASER INTERFEROMETRY

Janusz Pienkowski

Abstract

Diode lasers are becoming increasingly important in length metrology. We demonstrate construction of a simple single-frequency diode laser 632,8 nm, used as a frequency standard in the laser interferometers. We present two different systems applied for frequency stabilization of diode laser . For diode laser used as the secondary standard, the system stabilizes diode temperature, the frequency stability of the laser reaches value 1 part in 10⁶. For diode laser used as the primary standard is developed stabilization system using narrow absorption in iodine , the frequency stability of constructed diode laser reaches value 1 part in 10¹⁰.
