modulated laser meaning in Chinese
已调制激光
Examples
- Study of modulated laser interferometry for piezoelectric characteristic measurement of piezoelectric ceramic
压电陶瓷压电特性的激光调制法测量研究 - The clock control da chip of mb40978 converts rgb digital vedio singal into amplitude - modulated rgb pulse that is magnified and inner - modulate laser
经过处理的rgb视频数字信号经过时钟控制的da转换和一级驱动，产生调幅脉冲信号，实现半导体激光器的内调制。 - The present invention provides a wideband wavelength converter with four - wave - mixing , which includes a modulated laser diode , a modulator , a first and second polarized controller , a first , second and third tunable lasers , a optical coupler , a soa wavelength converter and a multiplexer
本发明系提出一种宽频四波混合波长转换装置，其包含调变雷射光源、光调变器、第一及第二极化控制器、第一、第二及第三可调式雷射、光耦合器、半导体光放大器、及一多工器。 - At present , signal pulses produced by directly modulated laser diodes have been used in optical fiber communication systems . the experiment reveals that the optical pulses from directly modulated laser diodes are far from gaussian and have near - rectangular temporal profiles with much sharper leading and trailing edges , and then a super - gaussian model , which assumes that an incident optical pulse has a super - gaussian profile , may be more suitable
但在实际的光通信系统中，人们常采用由直接调制半导体激光器产生的光脉冲作为信号脉冲，而实验结果表明这种脉冲具有比高斯脉冲更为陡峭的前沿和后沿，其脉冲形状更接近于超高斯分布，并且通常还带有一定量的啁啾。 - The wakefield excited by an ultrashort and ultrahigh laser pulse propagating through tenuous plasma can accelerate electrons to extreme high energy . this can be used as a mechanism to design minitype electron accelerator . this thesis is devoted to studying those issues relevant to the wakefield accelerator , namely the laser wakefield accelerator ( lwfa ) , laser wakefield accelerator driven by multiple pulses ( mp - lwfa ) , plasma beat wave accel - erator ( pbwa ) and self - modulated laser wakefield accelerator ( sm - lwfa )
