Fujikura has achieved an output power of 30 W from a Q-switched pulsed fiber laser with a pulse width about 100 ns for the first time in the world. Following the achievement, we commercialized a 70 W output pulsed fiber laser . In the article, we describe our activities on high-power pulsed fiber lasers, and introduce our 70 W output products. Fujikura’s advanced and original functions of pulse...

this paper presents a new method to reduce consumption power in flash adc in 65nm cmos technology. this method indicates a considerable reduction in consumption power, by removing comparators memories. the simulations used a frequency of 1 ghz, resulting in decreased consumption power by approximately 90% for different processing corners. in addition, in this paper the proposed method was desig...

The bias-pumped gain-switched fiber laser proposed by us is considered a novel pulsed fiber laser based on a new pulsing mechanism. With a certain signal power seeding, synchronization of temporal evolution can be kept between the output signal laser and the pump. The seed laser can be supplied conveniently by a CW pump power which is named bias pump power. A pulsed pump is responsible for shap...

Flip-flops is perilous timing elements in digital circuits which have a huge influence on the circuit speed and power consumption. The performance of flip-flop is an significant element to regulate the efficiency of the entire synchronous circuit.This paper recommends a low-power and area-efficient shift register using pulsed latches. Therefore area and power consumption are reduced by substitu...

Pulsed eddy current inspection techniques were derived from the conventional eddy current testing technology, based on the fundamental principle of an eddy current coil, but using periodic ultrasound pulses. The authors first introduce the principle of pulsed eddy current inspection and some experimental measurement results using pulsed eddy current equipment. This technology can be applied to ...

Low-power design is becoming a crucial design objective due to the growing demand on portable applications and increasing difficulties in cooling and heat removal. A clock distribution network (CDN) delivers the clock signal which act as a reference to all sequential elements in the synchronous systems. The clock distribution network consumes a considerable amount of power in electronic devices...
