1064 nm laser diode (PDF)

Technology

  • DBR Single-Frequency Laser Chip
  • AlGaAs QW Active Layer
  • Epi designed for high reliability

Features

  • Applications for the 1064 nm  laser diode include fiber amplifier seeding, second harmonic generation, spectroscopy, difference frequency generation, and low power DPSS replacement. It is often used as a Nd:YAG replacement.
  • Available in several package styles
  • Pulsed operation for spectral stability at short pulse lengths
  • High power for CW applications
  • High Slope Efficiency
