LBO is an excellent NLO crystal for OPOs and OPAs which has a widely tunable wavelength selection and significant powers. The exceptional Homes of variety I and sort II phase matching along with the NCPM go away a major room from the analysis and programs of LBO's OPO and OPA.

You should look at the wavelength and energy of one's laser resource and decide on a crystal that may be transparent with the specified wavelength and will stand up to the laser power. And lastly, other aspects like the thermal steadiness, optical homogeneity, and nonlinear optical coefficient of your crystal also need to be considered.

Lithium triborate (LBO) nonlinear crystal is Probably the most utilised crystal for harmonics era for brief and long pulse apps. As a result of it’s rather modest walkoff angle very long crystals might be employed what will allow to achieve substantial conversion performance. A Distinctive case of LBO crystal software is actually a non-important section matching (NCPM) for harmonics generation.

Raman spectroscopy may be used to identify impurities and defects in LBO nonlinear crystals that can have an impact on their effectiveness in a variety of applications. Raman spectroscopy will also be used to determine the crystal high quality and phase purity.

linear absorption, that may trigger heating at large optical electric power concentrations, so the section matching is disturbed, and thermal lensing may occur

The most typical utilization of LBO is In brief pulse, significant pulse rate lasers; the higher electric power density the higher. It is also quite well matched for non-critical period matching (NCPM) for frequency conversion of CW and quasi-CW radiation, at ninety% conversion efficiency with no get more info walk-off.

In laser cooling, frequency doubling is utilized to cool atoms and molecules to really small temperatures for numerous apps, which include quantum computing and atomic clocks. In quantum optics, frequency doubling is utilized to produce entangled photon pairs for quantum details processing.

LBO Crystals show high thermal stability and continue to function proficiently around a broad temperature vary. This wide array permits adaptable system design and makes certain that the crystal overall performance is not really compromised, even under fluctuating temperature conditions.

In the situation of ultrashort pulses the significant team velocity mismatch enforces the usage of a shorter crystal, which requires superior optical intensities for your specified conversion efficiency.

Diode pumped strong point out lasers with frequency changing LBO are very dependable, compact, and use less Electrical power than the standard lasers they frequently change. In lots of circumstances there was no suitable or very affordable laser to execute the capabilities that DPSS lasers have enabled.

Inspect the crystal surface area for dust and stains by Keeping it near a dazzling seen-mild resource. Viewing at diverse angles will help see scattering from dust and stains. The crystal surface should be cleaned as described beneath if dust and stains are observed.

The magnitude from the effective nonlinear coefficient depends on the nonlinear tensor parts and around the used stage-matching configuration. A high nonlinearity is important specially When the achievable optical intensities are small.

Sum-frequency technology (SFG) is often a nonlinear method that requires the conversion of two input photons into only one output photon that has a frequency equal to the sum of the enter frequencies. LBO nonlinear crystals Possess a high nonlinear coefficient, that makes them ideal for efficient SFG.

LBO nonlinear crystals have distinctive Houses that make them perfect for various applications in optics and photonics. This chapter discusses several of the most common programs of LBO nonlinear crystals.
