News: Nd:YAG Produces 2.8W of Blue Light by Photonics

BIBO (BiB3O6) is a newly developed Nonlinear Optical Crystal. It possesses large effective nonlinear coefficient, high damage threshold and is non-hydroscopic. It's nonlinear coefficient is 3.5 - 4 times higher than that of LBO, 1.5 -2 times higher than that of BBO. It can efficiently frequency doubling the 946nm to produce blue laser at 473nm.

Advantages:

  • Broad transparency range from 286nm to 2500nm

  • High optical homogeneity (dn10-6/cm) and being free of inclusion

  • Large effective SHG coefficient (about 9 times that of KDP)

  • High damage threshold

  • Wide temperature-bandwidth 

  • Inertness with respect to moisture 

Application:

  • SHG and THG for middle and high power Nd: lasers at 1064nm 

  • SHG and THG of high power Nd: lasers at 1342nm & 1319nm for red and blue laser

  • SHG for the Nd: Lasers at 914nm & 946nm for blue laser

  • Optical Parametric Amplifiers (OPA) and Oscillators (OPO) application
