A) First, is the Nonlinear crystal transparent at the involved wavelengths and phase-matchable?
B) If the answer is yes, then what’s the damage threshold, effective nonlinear coefficient and group velocity mismatch (for ultra fast laser)?
C) Chose suitable crystal sizes according to your laser power and pulse width, then calculate conversion efficiency.
D) Finally, balance the cost, conversion efficiency and environment condition.
How to choose a Nonlinear crystals?
NLO Crystals include BBO Crystal, LBO Crystal, LiNbO3 Crystal, MgO:LiNbO3 Crystal, DKDP&KDP Crystal, KTP Crystal and KTA Crystal etc. A-Star collect especial carefully for the inside material quality and polish in quickest time. The BBO Crystal is the most advantage from A-Star Photonics.
