Optical recording in the blue using a frequency-doubled diode laser

View publication


We have developed a 428-nm blue laser source based on resonator-enhanced frequency doubling of a GaAlAs diode laser and have used this source to demonstrate writing and reading on an MO disk. The power, beam quality and noise of the blue laser are sufficient for high-density optical recording.
