LBO allows temperature-controllable non-critical phase-matching (NCPM) for 1.0-1.3 m, Type I SHG, and also provides room temperature NCPM for Type II SHG at 0.8-1.1 m. It possesses a relatively large angular acceptance bandwidth, reducing the beam quality requirements for source lasers.
We offer Positioning Mount 5APH59T-1 for Nonlinear Crystal Housing.
|Broad transparency range from 160 nm to 2600 nm|
|Relatively large effective SHG coefficient (about three times that of KDP)|
|High damage threshold (18.9 GW/cm2 for a 1.3 ns laser at 1053nm)|
|Wide acceptance angle and small walk-off|
|Type I and Type II non-critical phase matching in a wide wavelength range|
|AR@1064nm + 532nm||0 +/-5 deg||14.66 J/cm2 @1064nm; 11ns; 50 Hz|
Laser induced damage threshold (LIDT) measurements are performed on actual components produced by Altechna. Individual component’s LIDT depends on multiple parameters (substrate material, polishing batch, coating batch, storage conditions, etc). Damage threshold value reached for above individual components should be used for reference only but it is not guaranteed for all optics. Altechna can perform coating damage threshold testing service upon request.
