An intermediate complex ocean-atmosphere coupled model is used to simulate the characteristics of the mature phase locking of the La Nia event and explore the mechanisms of the locking of the La Nia event mature phase to the end of the year.

Integration of Phase-locked Function Into Digital Circuit Design;

By means of experimental investigation of the unsteady flow near the orifice of synthetic jet actuator using PIV technology and using the phase-locked sample technique,72 instantaneous images and quantitative measurements during one actuating cycle for three different frequencies 10,20,30 Hz are obtained.

A W-band phase-locked system using Gunn VCO was developed.

The phase-locking of two photonic crystal fiber(PCF) lasers is studied experimentally by using Michelson cavity technique,and 47 W coherent output power is obtained.

Based on the injection-locking principle,the phase-locking mechanism of axisymmetric folded-combined CO2 laser is analyzed.

Beam coherent combination of two photonic crystal fiber(PCF)lasers is experimentally studied by using self-imaging resonator technique,and phase-locking of the two PCF lasers is achieved.

Thanks to the specially designed all-fiber coupling loop,the total loss of the phase locking array is reduced remarkably,and effective mutual injection coupling occurs between the component fiber lasers,so that the phase locking of the array is achieved.

It is theoretically found that phase locking high-order lateral modes of laser diode array(LDA)with a short external cavity can be realized.

A novel phase locking scheme of fiber lasers is proposed based on common ring coupled cavity and single mode fiber filtering, which provides a new and effective method to improve the stability, efficiency and expandability of the general passive coherent array.
