例句與造句

1. A "'laser diode "', or "'LD "'also known as "'injection laser diode "'or "'ILD "', is an electrically pumped semiconductor laser in which the active laser medium is formed by a p-n junction of a semiconductor diode similar to that found in a light-emitting diode.
2. Forward electrical bias across the laser diode causes the two species of charge carrier  depletion region, devoid of any charge carriers, forms as a result of the difference in electrical potential between " n "-and " p "-type semiconductors wherever they are in physical contact . ) Due to the use of charge injection in powering most diode lasers, this class of lasers is sometimes termed " injection lasers, " or " injection laser diode " ( ILD ).
3. It's difficult to find injection laser diode in a sentence. 用injection laser diode造句挺難的
