Research News: Doubling the frequency of light from an (Al,Ga)As laser quadruples its spot density and also, therefore, the amount of information which can be stored on an optical disc. By varying the lithium content of the title compound a frequency doubling material has been developed which can be tuned from 720 to over 920 nm producing a highly efficient blue laser capable of high‐density optical recording.
