Product Description:
Lithium Triborate (LiB3O5 or LBO) is an excellent nonlinear optical crystal. LBO crystal and its NLO devices now are produced, manufactured and marketed by CRYSTRONG.
• Wide range of transparency (160-2600 nm, see Figure 1)
• High optical homogeneity (δn ≈ 10-6 /cm), and being free of inclusion
• Relatively high SHG efficiency (about 3 times that of KDP)
• High damage threshold
• Wide acceptance angle and small walk-off
• Type I and type Ⅱ non-critical phase matching (NCPM) in a wide wavelength range
• Spectral NCPM near 1300 nm
• Strict quality control
• Large crystal size, aperture up to 55 x 55 mm2 and length up to 60 mm
• AR-coating, mounts and re-working services
• A large quantity of crystals in stock
• Fast delivery (15 days for polished only, 20 days for AR-coated)
