- With the rapid development of high speed and high capacity fiber communication and optoelectronic components , the coupling efficiency of laser diode ( ld ) and single mode fiber ( smf ) has become the most fundamental problem for engineers and researchers to solve
隨著高速度大容量光纖通信和光電子器件的迅猛發(fā)展，半導(dǎo)體激光器( ld )與單模光纖( smf )的高效耦合日益受到人們的重視。 - Through analyzing constitute and mechanism of high power laser diode ( ld ) fiber coupling module , the effects on reliability of ld fiber coupling module are detailed as following : crafts of coupling and encapsulation , electricity factors and ld itself
摘要文章從高功率半導(dǎo)體激光器光纖耦合模塊的組成和各個(gè)部分的機(jī)理出發(fā)，詳細(xì)分析了影響其可靠性的因素，主要有以下三個(gè)方面：激光器自身的因素、耦合封裝工藝和電學(xué)因素。 - It has a broader absorption band at 808 nm which is emitted by laser diode ( ld ) . therefore , nd : cngg is suitable for ld pumping , the ld pumped all solid - state lasers can be made by using nd : cngg . in this study , nd : cngg single crystals of 25mm in diameter and above 80mm in length were successfully grown by the automatically pulling method from the melt
摻釹鈣鈮鎵石榴石(簡(jiǎn)稱(chēng)nd : cngg )是一種新型激光晶體,該晶體熔點(diǎn)低( 1470 ) ,具有無(wú)序結(jié)構(gòu),在通用的808nm半導(dǎo)體激光二極管( ld )發(fā)射波長(zhǎng)區(qū)有寬吸收帶,因此很適合ld泵浦,可做成ld泵浦全固態(tài)激光器。 - As the extensive application of the semiconductor laser diode ( ld ) , it become more and more important to evaluate the quantity of laser beam . far - field divergence angle of laser beams is an important parameter about value of laser quality . not only the laser divergence peculiarity in the distance is reflected , but also quality of the correlative laser apparatus and the laser transmission is exactly known
隨著半導(dǎo)體激光器日益廣泛的應(yīng)用,對(duì)激光光束質(zhì)量的評(píng)價(jià)越來(lái)越重要,而激光光束遠(yuǎn)場(chǎng)發(fā)散角是評(píng)價(jià)激光質(zhì)量的一個(gè)重要參數(shù),它不但能反映遠(yuǎn)距離傳輸時(shí)的激光發(fā)散特性,而且能準(zhǔn)確評(píng)估出半導(dǎo)體激光器的品質(zhì)及激光的傳輸質(zhì)量。
