Why 878.6nm is the Smart Choice for DPSS Pumping?

The 878.6nm center wavelength closely matches absorption bands of Nd:YAG and Nd:YVO₄ crystals, providing:

  • Lower quantum defect and reduced thermal lensing
  • Higher optical-to-optical conversion rates
  • Improved beam quality and system efficiency
  • Compatibility with volume Bragg grating (VBG) stabilization

Compared to conventional 808nm sources, the 878.6nm spectrum ensures long-term performance and higher energy output in demanding pump applications.
