 By adding an etalon inside BBO-3B II OPO device, the BBO-3B II Et gives an easy approach to get high resolution out of an OPO system. The insertion of the etalon model is very straight forward and the whole spectral range of the BBO-3B II OPO could be covered by 5 sets of etalons. Two resolution options are offered. 


Specification Value Comments
Tuning Range 420 nm ~ 580 nm, 
900 nm ~ 2200 nm
pumped @ 355 nm
Nd:YAG pump requirement >100mJ @ 355nm, narrow bandwidth, SLM preferred  smooth profile (gaussian or flat top)
Bandwidth 0.2cm-1 or 0.01cm-1, depends on choice of etalon we offer 0.2cm-1 and 0.01cm-1as two options
Pulse width 2 ns shorter than pump pulse depends on actual pump pulse length
Beam diameter 2-5 mm  depends on input pump beam size
*All specifications are subject to change without notice. 
1. For your specific pump laser, please consult with U-Oplaz for suitability for pumping BBO-3B II Et.

Physical Layout: 

Same as BBO-3B II, could be upgraded from BBO-3B II by adding the modularized tuning block for BBO-3B Et.
