LBO
LBO has many unique characteristics that contribute to its wide use as a nonlinear optical crystal. LBO's high damage threshold makes it the preferred choice for high power applications. However, inadequate AR coatings often lower the damage threshold of the device. FOREAL SPECTRUM combines the highest quality material with our excellent in-house coating capability to provide the best LBO crystals available.

BBO
BBO has a wide transmission range, high nonlinear efficiency and is widely used for harmonic generation, optical parametric amplifiers, and optical parametric oscillators.

Brewster angle cut is available. Each BBO crystal has a protective dielectric coating that protects the polished surfaces from fogging due to ambient moisture. The protective coating also reduces reflection from the polished surface and improves transmission for all wavelengths that are used. Single-band, dual-band and broadband anti-reflection (AR) coatings are available. One-year warranty for all products under proper use.

Note:
BBO has a low susceptibility to the moisture. The user is advised to provide dry conditions for both the use and storage of BBO. BBO is relatively soft and therefore precautions should be taken to protect its polished surfaces. When angle adjustment is necessary, the small acceptance angle of BBO should be taken into account.
