Beta Barium Borate (BBO – β-BaB2O4):

• Properties: Wide transparency range from the ultraviolet (about 190 nm) to the infrared (about 3500 nm), high damage threshold, and excellent nonlinear optical coefficients.
• Applications: Frequency doubling, OPOs, and other applications requiring high power and UV generation.

Lithium Niobate (LiNbO3):

• Properties: Strong electro-optic and nonlinear optical effects, wide transparency range, but has a relatively low damage threshold.
• Applications: Widely used in integrated optics as modulators and switches, as well as in terahertz wave generation.

Potassium Titanyl Phosphate (KTP – KTiOPO4):

• Properties: Efficient at room temperature, high optical damage threshold, and effective phase matching properties.
• Applications: Frequency doubling of Nd:YAG lasers, OPOs, and in medical and dental lasers.

Lithium Triborate (LBO – LiB3O5):

• Properties: Broad transparency range, high damage threshold, and suitable for high-power applications.
• Applications: Frequency doubling, especially for high power lasers, and for generating UV light through SHG.

Potassium Dihydrogen Phosphate (KDP – KH2PO4) and its isomorph Potassium Dideuterium Phosphate (KD*P – KD2PO4):

• Properties: High electro-optic coefficients and good UV transmission but lower damage thresholds.
• Applications: Frequency doubling, especially for high-energy lasers like those used in inertial confinement fusion.
