5 Simple Statements About LBO Crystal Explained
Blog Article
The optimum angle is dependent upon the type of nonlinear procedure, the wavelength, and also the crystal thickness. Other strategies for reaching period-matching in LBO nonlinear crystals include temperature tuning and quasi-stage matching.
You need to consider the wavelength and electric power within your laser resource and select a crystal that may be clear on the given wavelength and may face up to the laser electrical power. And lastly, other components like the thermal security, optical homogeneity, and nonlinear optical coefficient of the crystal also should be thought of.
Important Phrases: Nonlinear Crystals , SHG crystal , SFG crystal , LBO Crystal Lithium Triborate (LiB3O5 or LBO) is actually a kind of nonlinear crystal that is commonly used in the technology of significant-electricity laser radiation. It's a high damage threshold along with a broad transparency vary from the ultraviolet for the in close proximity to-infrared area, which makes it appropriate for many different laser apps.
Possessing the crystal Slash for NCPM and trying to keep the crystal at specific temperature, the walkoff angle is nearly zero, that's why it permits to have a very extended crystal and realize excellent conversion effectiveness. The LBO crystal is usually used to generate second and 3rd harmonics of neudymium based mostly lasers like Nd:YAG, Nd:YVO4. A different critical software of the LBO crystal is frequency conversion in optical parametric oscillators (OPO).
With regards to the optical Qualities of LBO Crystals, they in truth existing a formidable portfolio. The extensive transparency vary, stretching with the deep ultraviolet to significantly infrared spectrum, enables LBO Crystals to connect with an enormous variety of laser gentle sources, amplifying their versatility in different purposes.
Over-all, The combination of LBO Crystals into laser technological know-how has pushed the boundaries of what we can easily reach with light, lighting the path to a brighter, a lot more illuminated future.
SHG and THG for Center and superior electric power Nd: lasers at 1064 nm for health-related, industrial and military services purposes
Excessive optical intensities through Procedure might instantaneously problems a crystal. Regrettably, nonlinear crystals generally should be operated not much from their optical injury threshold to obtain a sufficiently higher conversion performance. This implies a trade-off amongst conversion efficiency and crystal life time.
L-B-O, what on earth is it good for? Totally the top frequency doubling and tripling crystal any time you are seeking the most strong and destruction resistant product.
Optical parametric amplification (OPA) is often a nonlinear system that will involve the conversion of the higher-Electricity photon into two lower-Electricity photons. LBO nonlinear crystals Have a very higher nonlinear coefficient, which makes them ideal for effective OPA.
Inspect the crystal surface for dust and stains by holding it close to a brilliant seen-mild supply. Viewing at distinct angles can assist see scattering from dust and stains. The crystal floor needs to be cleaned as described click here below if dust and stains are found.
The most common programs is frequency doubling, wherever LBO Crystals competently convert the frequency of the superior energy laser, properly halving the wavelength and opening up a spectrum of alternatives for laser purposes.
This big selection empowers them to communicate with diverse laser sources, opening up a broad spectrum of applications throughout various scientific and industrial sectors.
Crystals which happen to be non-critically phase-matched in the crystal oven may well show issues once the crystal temperature is adjusted much too rapidly or too frequently. Particularly, anti-reflection coatings could possibly be destroyed resulting from unique thermal expansion coefficients of your concerned components.
