BIBO crystal (bismuth triborate) is a relatively novel nonlinear product compared with BBO and LBO crystals. BIBO crystal surpasses BBO with regard to its powerful nonlinearity, although also giving a broader bandgap compared to KTP crystal.
Inertness to Dampness: BIBO crystal is inert to humidity, which means it does not degrade or get rid of its optical Attributes when exposed to humidity. This helps make BIBO a far more secure and reliable choice for optical apps in several environments.
Almost all of the normal nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the fundamental laser radiation are available from stock. Shopper-certain Proportions and AR coatings also are provided at competitive price ranges.
Crystal life span will also be strongly depending on the material top quality, Though specified degradation phenomena appear to be intrinsic limits of the fabric.
BIBO crystals can be utilized as superior-efficiency frequency doubling and frequency summing products and have broad software potential customers in optical parametric oscillation (OPO).
GWU-Lasertechnik has greater than thirty years of practical experience in distributing laser crystals. Choose GWU to get pleasure from our vast know-how and in-discipline experience!
At present, as A form of wonderful nonlinear 2nd harmonic crystal, it may be used to provide superior efficiency crystal of green or blue laser.
Operation of nonlinear crystals at temperatures underneath space temperature (to obtain section matching) is usually problematic, as it may well cause condensation of drinking water about the crystal surfaces In case the encompassing air is just not extremely dry.
Even though the nonlinear coefficient of KTP crystal is huge, the laser destruction threshold is minimal, which will trigger challenges for example refractive index adjust and transmission reduction. BIBO crystal has increased laser hurt threshold and higher 2nd harmonic conversion performance. Even though LBO and B-BBO are by far the most practical, They may be modest in dimensions and possess sure hygroscopicity, while BIBO crystals are non-wet and can develop to huge dimension. get more info These rewards empower BIBO crystals being commonly applied.
Crystals that are non-critically period-matched inside a crystal oven may well exhibit challenges once the crystal temperature is transformed too quickly or much too usually. Specifically, anti-reflection coatings might be harmed because of diverse thermal enlargement coefficients from the included products.
Bismuth Triborate (BiB3O6 or BIBO) is a newly designed nonlinear optical crystal. It possesses substantial effective nonlinear coefficient, higher injury threshold and inertness with respect to dampness.
China BIBO crystals may be used don't just as large-performance frequency doubling and frequency summing devices, but also have broad software prospects in the field of optical parametric oscillation (OPO), and What's more, it has an important application inside the successful technology of ultrabright entangled photons through blue pumped Spontaneous Parametric Down Conversions (Also Know as SPDC).
The magnitude on the effective nonlinear coefficient is dependent upon the nonlinear tensor components and about the used phase-matching configuration. A substantial nonlinearity is essential notably if the achievable optical intensities are minimal.
Because the 2nd harmonic (SHG) could be widely accustomed to produce coherent obvious mild and ultraviolet radiation, people today concentrate to it, but the normal nonlinear crystals for instance KDP, LBO, KTP, B-BBO also have many shortcomings. BIBO crystal is a whole new kind of nonlinear crystal. When compared with KDP crystal, it tends to make up for that disadvantage that KDP crystal can increase in large measurement but dissolve in h2o.
