AbstractThe performance of a new liquid Nitrogen cooled Fabry-Perot etalon for imaging at 3-5µm is described. Capacitance sensors monitor the etalon mirror spacing and parallelism, and error signals produced as a consequence of changes in these parameters are used in a feedback loop with piezoelectric actuators for active cavity control. These new cryogenic etalons are designed to be compatible with the Queensgate Instruments Ltd CS100/ET servo-stabilized Fabry-Perot system.The cryogenic etalon has a clear aperture of 50mm and a nominal mirror spacing of between 5 and 60µm. It is coated for the 3 - 5µm spectral region, although coatings are also available for the 2 - 2.5µm and 8 - 13µm regions. Under servo-control at operating temperature the etalon has a response time of 30 msec and a minimum cavity tuning range of ±3µm about the nominal cavity length, corresponding to approximately 3 orders of interference at the midrange wavelength of 4µm.

Important Study

The Semiconductor laser frequency stabilization is the important study topic because of its increasing popular. We introduce a simply experimental setup method of the frequency stabilization of a 780 nm diode laser by only a tiny current in the laser audio modulation, photodiode receiver, and locking the transmission peaks. Use this method, the laser can be locked to the resonance peak of the Fabry-Perot cavity. The linewidth of laser is below 400 kHz, and it runs continually above 3 hours.

This paper reports a new kind Terahertz generator using tunable dual-wavelength generator based on MEMS technology, which are developed based on free-carrier effect (FCE) and thermo-optic effect (TOE) [1-3]. The approach provides a wide tuning range from 0 to 15 nm by adjusting the current of laser diodes and heating up common silicon Fabry-Perot (FP) external cavity. Compared to the conventional optical generation methods, this method has fast tuning speed (<1 ms), small size (2.2 mm 0.8 mm), high integration and quite stability performance.
