LBO (Lithium Triborate) Crystal
LBO Crystal is an excellent nonlinear optical crystal grown by the top-seeded solution growth method. It is widely used for Second Harmonic Generation (SHG) and Third Harmonic Generation (THG) of Nd:YAG, Nd:YLF, and Nd:YVO4 lasers. LBO is one of the most practical nonlinear optical materials for UV and visible laser applications due to its wide transparency range and high damage threshold.
Main Applications
- 1. Second Harmonic Generation (SHG) and Third Harmonic Generation (THG);
- 2. Optical Parametric Amplifiers (OPA) and Optical Parametric Oscillators (OPO);
- 3. Frequency doubling of high-power Nd-doped lasers;
- 4. UV and visible laser generation applications.
Product Advantages
- 1. Wide transparency range (160nm - 2600nm);
- 2. High optical homogeneity (δn≈10⁻⁶/cm) and free from inclusions;
- 3. Large effective nonlinear coefficient;
- 4. Wide acceptance angle and small walk-off angle;
- 5. Supports Type I and Type II Non-Critical Phase Matching (NCPM) over a broad wavelength range;
- 6. High laser damage threshold (up to 18.9 J/cm² at 1053nm, 1.3ns pulse);
- 7. NCPM available near 1300nm.
