Unmodulated diode laser stabilized by the Zeeman modulation technique

Autor: Ersoy Sahin

Publikováno v: Applied Physics B. 127

The extended cavity diode lasers’ frequencies were stabilized by the usage of the 1st and 3rd derivatives signals obtained from hyperfine resonances of the 87Rb D2 line with the Zeeman modulation technique. By using the 3rd derivatives of the F = 1
