1.Fig. 1 is a block schematic diagram of a direct up-conversion transmitter 100.

4.Luminescence Properties and Up-Conversion Mechanism of Er~(3+)-Yb ~(3+)-Tm ~(3+)Co-Doped CdF_2:PbF_2-Based Glass
5.Under 980 nm excitation, we obtained five intense up-conversion luminescence bands in Er 3+-Yb 3+-Tm 3+co-doped CdF 2:PbF 2-based glass as follows: infrared(800 nm), red(645 nm), green (545 nm and 525 nm), blue(480 nm ) and violet(407 nm) up-conversion luminescence.
6.Strong green up-conversion emission was observed for the first time in europium and dysprosium co-doped strontium aluminate (SrAl 2O 4:Eu 2+,Dy 3+) phosphor under 980 nm infrared excitation at room temperature.
7.Firstly, the basic theory of digital up/down conversion is introduced, and then, the available structures of Cascaded Integrator Comb (CIC), which includes the traditional CIC, Sharpen CIC (SCIC) and CIC+ISOP (Interpolated Second-Order Polynomial), are compared.
8.The transmitter does the work of a burst transmission, its encoding and framing are all implemented in the link control part, the base-band process part does the spreading, FIR filtering and up frequency conversion.
9.FOLLOW-UP OBSERVATION ON NATURAL CONVERSION OF RESIDUAL MICROFILARIEMIA OF FILARIASIS MALAYAN AT LATE STAGE OF CONTROL PROGRAM
10.SRS possesses many attractive features, i.e. beam clean-up, pulse compression, no need for phase matching, and high conversion efficiency.
