BIBO Crystal Fundamentals Explained

Hygroscopic crystal elements deteriorate when they're not often kept in adequately dry air (or a dry purge fuel). This applies e.g. to KDP and BBO, As well as in a lesser extent to LBO. It could be useful to keep such a crystal in a to some degree elevated temperature, which makes it easier to retain it dry.

Laser processing and product dealing with: In the sector of laser processing and substance dealing with, the high ability functionality of BIBO crystals makes them a vital element while in the manufacture of higher Electricity density laser beams.

With a big powerful nonlinear coefficient, superior destruction threshold, and inertness to humidity, BIBO crystal features various rewards over other nonlinear optical supplies for example LBO and BBO.

Also, it may be extremely attractive to use a crystal substance which may be critically stage-matched at space temperature due to the fact noncritical period matching normally involves the Procedure from the crystal in a temperature-stabilized crystal oven. Nevertheless, the feasibility of significant stage matching might be specified only for sufficiently superior peak powers.

Dust and stains on crystal surfaces may cause scattering/reduction of sunshine and can even respond with light-weight to damage optical surfaces at a superior incident laser electrical power.

Observe that even if the nominal depth is beneath the nominal destruction threshold, there may be troubles as a consequence of fluctuations within the beam electrical power or community depth (e.g., if a beam profile has “scorching spots�?, or as a result of isolated defects in a very crystal, which are far more delicate compared to the standard crystal substance.

And is especially beneficial for building wavelengths in the eco-friendly and blue spectrum by way of more info ongoing-wave (CW) radiation. The elevated efficient nonlinearity of BIBO crystal not merely enhances the performance of your SHG process but also facilitates the utilization of shorter crystal lengths—an indispensable attribute when endeavoring to engineer compact laser systems.

In the case of ultrashort pulses the large group velocity mismatch enforces the use of a shorter crystal, which requires high optical intensities for a offered conversion efficiency.

Borates such as LBO and BBO also get the job done effectively in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.

  )  to blow off dust along with other free contaminants 1st. If a dry nitrogen line is obtainable within the lab, an air gun will also be made use of  to blow away dust particles. Blow off the surface Carefully. Do not blow from the crystal itself out of your hand!

This combination makes BIBO crystal extremely suited to harnessing the phenomenon of second harmonic technology (SHG) in sound-state lasers and laser diodes.

The magnitude from the powerful nonlinear coefficient depends on the nonlinear tensor components and within the utilized stage-matching configuration. A substantial nonlinearity is significant significantly if the achievable optical intensities are reduced.

Our crystals are Employed in a wide range of applications, like many forms of nonlinear frequency conversion and electro-optics, but will also quantum technologies.
