This informative article dives deep into the advantages and special properties of BBO crystal and its paramount value in efficient frequency doubling and harmonics generation at 266nm.
Optical parametric chirped-pulse amplification (OPCPA): We use OPCPA to ascertain our objects�?nonlinear conversion effectiveness and also stage-matching angle to get a given enter wavelength and sign/idler wavelengths.
The damage Assessment will likely be carried out on the same optic (consumer's optic will not be ruined). Screening may well bring about further expenditures or lead times. Get in touch with Tech Aid For more info.
BBO crystal stays probably the most flexible nonlinear optical crystals owing to its distinctive mixture of optical Houses (

Stage matching considerably enhances the conversion effectiveness and may be required to obtain adequate frequency-doubled mild for apps, but 2nd harmonic generation (SHG) will happen even though section matching just isn't carried out. The impact of period matching about the output intensity of SHG mild (I2ω) is illustrated in Determine 16.
Now Look at the most electric power density to that which can be specified since the LIDT for your optic. In case the optic was tested in a wavelength other than your working wavelength, the harm threshold must be scaled properly.
In combination with their use in laser frequency conversion, BBO crystals have discovered programs in electro-optic modulation and quantum optics experiments.
The lifespan of BBO crystals will vary enormously based on various elements. These incorporate how the crystals are applied, how They can be dealt with, and also the disorders where These are saved.
Little acceptance angle: BBO crystals have a small acceptance angle that limits the enter mild beam’s light beam divergence and major method top quality for effective regularity conversion.
The efficiency on the SHG course of action decreases significantly as the elemental beam diverges from its emphasis, since the pulse Electricity is distributed throughout a bigger beam cross area.
The event value is dependent upon the temperature gradient, rotation fee, pulling charge, soften makeup, and oxygen strain. We carefully keep track of these variables all through the development technique to guarantee the uniformity and top quality of your boule.
The temporal stroll-off is commonly regarded severe if the temporal lag exceeds the duration of the basic pulse. Intense walk-off may lead to temporal lag that irreparably raises the period in the output next harmonic pulse.
Inspect the crystal floor for dust and stains by website Keeping it near a brilliant seen-light-weight supply. Viewing at unique angles might help see scattering from dust and stains. The crystal surface area should be cleaned as explained beneath if dust and stains are discovered.
