<title>Optical data storage requirements on short-wavelength laser sources</title>

Abstract

Advances in diode-laser-based nonlinear blue sources as well as blue injection lasers have generated interest in using these sources for optical data storage. Recording results using a 429-nm, frequency doubled-diode laser are illustrative in understanding the requirement on these laser sources. A very stringent requirement on the laser source is the low cost necessary for high market penetration of the storage device.
