Diode Laser Frequency Standard for Laser Interferometry
نویسنده
چکیده
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 10. 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 10 .

Absolute distance measurements based on the frequency comb of a femtosecond pulse laser
We describe absolute distance measurements performed by exploiting the frequency comb of a femtosecond laser as a precision wavelength ruler. The frequency comb is first stabilized to a Rb atomic clock of time standard. Then multi-wavelength interferometry integrated with a wavelength-scanning scheme is implemented by tuning an external cavity diode laser to the pre-selected frequency modes of ...
متن کاملFrequency Noise Suppression of a Single Mode Laser with an Unbalanced Fiber Interferometer for Subnanometer Interferometry
We present a method of noise suppression of laser diodes by an unbalanced Michelson fiber interferometer. The unstabilized laser source is represented by compact planar waveguide external cavity laser module, ORIONTM (Redfern Integrated Optics, Inc.), working at 1540.57 nm with a 1.5-kHz linewidth. We built up the unbalanced Michelson interferometer with a 2.09 km-long arm based on the standard...
متن کاملTuning extension of a Difference-Frequency generation up to 100 nm using V-shaped external-cavity for the pump laser
In this research, tunability of a commercial diode laser has extended to about more than ± 11 nm using a V-shaped external-cavity fabricated around the laser. Although under normal condition it can be tuned up to about ± 4 nm just by changing its temperature and injection current. Such modified diode laser has then used in a difference-frequency generation (DFG) experimental setup as pump sourc...
