Both equally wide-bandwidth pulses and temporal walk-off trigger a discount in the conversion effectiveness, as well as worsen the optical top quality of the next harmonic pulses. The right crystal thickness should be selected to reduce both consequences.
This fantastic-tuning capability ensures that BBO crystals can cater to both equally generic and remarkably specialised desires with equivalent finesse.
The Vitality in both equally waves propagates in directions determined by their Poynting vectors. Snell's law doesn't explain the route of Vitality movement, but it surely may be used to compute the way from the k-vector inside the crystal.
Crystal life time will also be strongly dependent on the fabric top quality, Despite the fact that specified degradation phenomena seem like intrinsic limits of the material.
Second harmonic generation (SHG): We employ SHG to measure our items�?nonlinear conversion efficiency and phase-matching angle for a supplied input wavelength. We ensure that our products fulfil the necessities for SHG applications.

Beta Barium Borate (BBO) crystals have been a topic of desire in the field of optics and photonics due to their one of a kind Qualities. In this post, we aim to reply ten frequent questions about BBO crystals, delivering a comprehensive comprehension of this interesting product.
BBO crystals are fragile and involve very careful dealing with to prevent harm to their surfaces. They should be taken care of with thoroughly clean, lint-free of charge gloves to prevent scratching or contaminating their surfaces. When not in use, BBO crystals ought to be saved in the great, dry place clear of immediate sunlight, as extended exposure to warmth and light-weight can degrade their optical Qualities.
BBO crystals also are Employed in electro-optic modulation, a method made use of to control the phase, polarization, or amplitude of a light beam. Moreover, they come across use in optical parametric oscillation, a process that generates two output waves from one particular input wave, and quantum optics, a area that explores the quantum interactions of sunshine and make a difference.
How are BBO Crystals Developed? BBO crystals are manufactured using the flux approach, which will involve melting a mixture of barium borate and barium fluoride and slowly and gradually cooling it to variety crystals.
As illustrated in the next desk, the shorter the crystal, the wider the reference pulse spectrum. The table under assumes a elementary Heart wavelength while in the in close proximity to-IR.
GWU-Lasertechnik has much more than 30 many years of working experience in distributing laser crystals. Pick GWU to reap the benefits of our extensive awareness As well as in-field encounter!
Optical parametric amplification (OPA): We website use OPA to evaluate our items�?nonlinear conversion effectiveness and section-matching angle for just a offered input wavelength and signal/idler wavelengths. We assurance that our products and solutions fulfill the specs for OPA purposes.
