LBO has a very low susceptibility to moisture. Users are advised to provide dry conditions for both the use and preservation of LBO.Polished surfaces of LBO requires precautions to prevent any damage. our engineers can select and design the best LBO crystal for you, if the main parameters of your laser are provided, such as energy per pulse, pulse width and repetition rate for a pulsed laser, power for a cw laser, laser beam diameter, mode condition, divergence, wavelength tuning range, etc. For thin LBO crystal, we can provide free holder for you.
