A Simple Key For BBO Crystal Unveiled
Blog Article
Optical parametric oscillation (OPO): We utilize OPO to ascertain our products�?nonlinear conversion effectiveness and phase-matching angle to get a offered enter wavelength and sign/idler wavelengths. We make specific that our things meet the requirements for OPO apps.
EKSMA Optics employs cookies to provde the very best buying experience. In case you continue on to employ our services, We'll presume which you comply with the usage of this sort of cookies.
We reduced our boule into smaller sized merchandise Based on customer specs employing a ruby blade, or twine saw machine. Following that, polish these pieces applying ruby powder or slurry on Solid iron or copper plates.
Borates such as LBO and BBO also operate properly in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
Second harmonic era (SHG): We employ SHG to measure our objects�?nonlinear conversion efficiency and stage-matching angle for any given input wavelength. We warranty that our things fulfil the requirements for SHG applications.
If the crystal surfaces are still “soiled�?right after the above cleaning methods, the surfaces may need been ruined. Remember to Make contact with us for rework in the crystals.

When pulse lengths are between one ns and 1 µs, laser-induced injury can manifest either as a consequence of absorption or a dielectric breakdown (consequently, a person should Look at both CW and pulsed LIDT). Absorption is both because of an intrinsic house of your optic or due to surface irregularities; As a result LIDT values are only legitimate for optics Assembly or exceeding the area top quality specs offered by a company.
We also layer our objects with anti-reflection levels to decrease illustration losses at the crystal surfaces.
Any scratches can degrade the optical effectiveness on the crystal and potentially induce hurt under substantial laser electrical power. For stubborn stains, a solution of moderate detergent or isopropyl Alcoholic beverages is often gently placed on the crystal surface area after which rinsed off with distilled drinking water.
BBO crystals are renowned for their Remarkable optical properties. Their large transparency variety permits them to function effectively across a broad spectrum, from ultraviolet to around-infrared gentle. This click here would make them incredibly multipurpose and ideal for many different applications.
As illustrated in the subsequent desk, the shorter the crystal, the broader the reference pulse spectrum. The table below assumes a basic Heart wavelength in the in close proximity to-IR.
In the case of ultrashort pulses the large group velocity mismatch enforces the usage of a shorter crystal, which involves substantial optical intensities for the specified conversion performance.
This tends to make them extremely long lasting and resilient, even more maximizing their suitability for challenging optical applications.
