BIBO crystal (bismuth triborate) is a comparatively novel nonlinear product when put next with BBO and LBO crystals. BIBO crystal surpasses BBO when it comes to its helpful nonlinearity, even though also offering a broader bandgap in comparison to KTP crystal.
Inertness to Dampness: BIBO crystal is inert to dampness, meaning it doesn't degrade or get rid of its optical Homes when subjected to humidity. This makes BIBO a more steady and trusted selection for optical applications in a variety of environments.
Inspect the crystal area for dust and stains by Keeping it in close proximity to a vibrant noticeable-light supply. Viewing at various angles will help see scattering from dust and stains. The crystal floor needs to be cleaned as explained down below if dust and stains are discovered.
The amount of the solvent may be modified for various crystal measurement Therefore the lens tissue is held moist for the whole drag but there's not any obvious trace of solvent around the crystal surface area following the drag is completed. Inspect the surface area and repeat if necessary, but only use Each and every sheet of lens tissue at the time.
Also, it may be remarkably attractive to employ a crystal material which can be critically stage-matched at room temperature because noncritical phase matching generally includes the Procedure of the crystal in a very temperature-stabilized crystal oven. Nonetheless, the feasibility of crucial period matching could be specified only for adequately substantial peak powers.
Dust and stains on crystal surfaces could cause scattering/loss of light and may even react with light to break optical surfaces at a substantial incident laser electrical power.
The selection with the most fitted crystal material to get a supplied software is usually far from trivial; it should really contain the consideration of many aspects. As an example, a superior nonlinearity for frequency conversion of ultrashort pulses does not assist Should the conversation size is strongly constrained by a significant here group velocity mismatch and the reduced harm threshold limitations the applicable optical intensities.
Scientific investigate and improvement: BIBO crystals also Engage in a crucial position in scientific study and growth. Its great nonlinear optical effectiveness delivers new instruments and alternatives for ultrafast phenomenon investigate, solid subject physics, biomedical imaging and other fields
In the case of ultrashort pulses the high group velocity mismatch enforces the usage of a shorter crystal, which involves large optical intensities for your given conversion efficiency.
Borates like 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 and also other loose contaminants first. If a dry nitrogen line is obtainable inside the lab, an air gun can even be made use of to blow absent dust particles. Blow from the surface area gently. Don't blow off the crystal by itself from the hand!
This combination would make BIBO crystal extremely fitted to harnessing the phenomenon of next harmonic generation (SHG) inside sound-condition lasers and laser diodes.
The Coating curves, transmittance curves, flatness reviews and area high-quality report below microscope for BiBO Crystal will likely be furnished when shipped.
Substantial Problems Threshold: BIBO crystal provides a superior harm threshold, letting it to withstand significant laser electricity without suffering problems. This characteristic can make BIBO ideal for use in high-energy laser programs.
