text: uv diode-pumped laser? do u know about dat? science hi,  a laser requires population inversion in order to work. in order to generate population inversion, one way is to use diode to "pump" the electrons to the conduction band.  so, a diode-pumped uv laser means it is a laser emitting uv (ultra-violet) light and the population inversion is generated by diode pumping.  please let us know how much you know about quantum mechanics and diodes so that we can answer your question more properly.  http://www.kodkodkod.com/index_files/submitquestion.htm  kodkodkod learning consulting
