“…In the cases mentioned above, i.e. when the laser diode is operated at a constant current, the laser frequency can be stabilized by one of the typical spectroscopic methods [1,[16][17][18], where some part of the laser light passes through an absorption cell. The narrow absorption signal is used for side-locking or peak-locking by an electronic controller of the laser frequency.…”

We have developed experimental methods for the generation of chirped laser pulses of controlled frequency evolution in the nanosecond pulse length range for coherent atomic interaction studies. The pulses are sliced from the radiation of a cw external cavity diode laser while its drive current, and consequently its frequency, are sinusoidally modulated. By the proper choice of the modulation parameters, as well as of the timing of pulse slicing, we can produce a wide variety of frequency sweep ranges during the pulse. In order to obtain the required frequency chirp, we need to stabilize the center frequency of the modulated laser and to measure the resulting frequency evolution with appropriate temporal resolution. These tasks have been solved by creating a beat signal with a reference laser locked to an atomic transition frequency. The beat signal is then analyzed, as well as its spectral sideband peaks are fed back to the electronics of the frequency stabilization of the modulated laser. This method is simple and it has the possibility for high speed frequency sweep with narrow bandwidth that is appropriate, for example, for selective manipulation of atomic states in a magneto-optical trap.

A new optical Doppler lidar receiving system which can measure Doppler-shifted incoherent scattering light has been proposed and tested. This system functions in a manner similar to two edge filters and consists of a single etalon, a polarization beam splitter, and mirrors that can guide scattered light into a single etalon with two different angles. These two incident angles are precisely adjusted by the polarization beam splitter and mirrors. Using this optical receiving system we can measure a moving target with a high sensitivity. Theoretical calculations show that this system will have a better optical sensitivity than a single edge system and will allow the use of incoherent Doppler lidar for wind velocity measurements.

High stability of semiconductor lasers have been shown useful in many applications areas,[such as optical communication, high-resolution spectroscopy quantum metrology, laser cooling and trapping[. With the rapid development of fiber optic dense wavelength division multiplexing system, we require laser source with high frequency stability in 1.5μm band. In this paper It is clear that temperature, cavity length and injection current have effects on frequency stability of FBG external cavity semiconductor laser by simulation experiments. Besides that, the frequency stabilization system is adjusted. Therefore, the frequency jitter spectra before and after locking are given and the experimental results are analyzed. The results show that after locking laser the typical frequency jitter is significantly improved comparing with frequency fluctuation in the condition of free running.
