Abstract: The disclosure provides a clock step control circuit and a method thereof. The clock step control circuit includes a clock divider, a multiplexer, and a controller. The clock divider receives a first clock signal and outputs multiple second clock signals. The multiplexer receives the second clock signals and outputs one of the second clock signals. The controller is coupled to the clock divider and the multiplexer.

The inorganic filler is encased in a carrier resin which is present in an amount of between 0.5% (wt.) to 15% (wt.) relative to the total weight of the thermoplastic layer.

Abstract: A low-profile dual-axial deflection device having deflection axes intersecting at a mirror surface and method for achieving dual-axis deflection are disclosed, the device including essentially three parts: a base and a fixing support for fixing and mounting; elastic kite-shaped seats and deflection support base providing deflection driving, and a mirror carrier, a mirror and flexible hinges and connecting stations for limiting deflection displacement of the mirror carrier. The present disclosure uses four piezoelectric ceramics to realize the output control of the deflection angle, and has high control precision and fast response. Simultaneous driving of four piezoelectric ceramics can realize dual-axis deflection of the mirror. The device adopts a sinking mirror structure, and the deflection axes intersect at the surface of the mirror, thereby reducing the optical path control error caused by the longitudinal displacement of the mirror during deflection.

Abstract: A robust method of stabilizing a diode laser frequency to an atomic transition is provided. The method employs Zeeman shift to generate an anti-symmetric signal about a Doppler-broadened atomic resonance, and, therefore, offers a large recapture range as well as high stability. The frequency of a 780 nm diode laser, stabilized to such a signal in Rb, drifts less than 0.5 MHz.sub.pk-pk (one part in 10.sup.9) in thirty-eight hours. This tunable frequency lock may be inexpensively constructed, requires little laser power, rarely loses lock, and may be extended to other wavelengths by using different atomic species.
