Optical parametric oscillation (OPO): We employ OPO to find out our products�?nonlinear conversion overall performance and stage-matching angle for just a specified enter wavelength and signal/idler wavelengths. We make selected that our things meet the requirements for OPO apps.
Typical cleaning of BBO crystals is likewise proposed to take care of their optical functionality. This may be performed employing a smooth fabric or lens tissue moistened with a delicate solvent, such as isopropyl alcohol.
The damage Examination will probably be completed on the same optic (consumer's optic won't be harmed). Tests may perhaps bring about more prices or guide situations. Make contact with Tech Assist To find out more.
BBO crystals might be bought from various suppliers specializing in optical products. It’s essential to select a highly regarded supplier to ensure the caliber of the crystals.
Soon after extraction, the BBO crystals are then Lower into the specified shapes and sizes. This chopping course of action is executed with precision devices to make certain the crystals are Slash correctly and cleanly.
Nevertheless, to completely employ the probable of BBO crystals, it truly is vital to be familiar with their Homes and how to handle and shop them thoroughly. These crystals involve mindful dealing with to prevent damage to their surfaces and may be stored in the dry, cool location to maintain their optical performance.
On the other hand, it’s crucial to Take note that though BBO crystals can handle substantial ability, they must however be utilized within their specified power array to circumvent likely injury and make certain ideal efficiency.
Besides their use in laser frequency conversion, BBO crystals have discovered programs in electro-optic modulation and quantum optics experiments.
Beam diameter is additionally imperative that you know when evaluating destruction thresholds. Although the LIDT, when expressed in models of J/cm², scales independently of spot dimensions; big beam sizes are more likely to illuminate a bigger range of defects which can result in better variances from the LIDT [four].
In apply, γ is nonzero in the event the polarization states of light inside of a laboratory reference body aren't matched to your intrinsic principal axes while in the crystal body. To orient The 2 reference frames together, e.g. the vertically polarized mild through the laser on the optical desk is parallel to check here during the crystal, we mount the nonlinear crystal inside a rotation phase to finely regulate γ to zero, to start with by eye utilizing the markings to the housing and then further, if essential, utilizing the SHG output electrical power as comments.
When comparing an LIDT specified for just a pulsed laser for your laser, it is critical to find out the subsequent:
BBO nonlinear crystal is usually a adverse uniaxial crystal. It provides period matching for various 2nd-order interactions Practically over its total transparency assortment. This transparency ranges from 185 nm to 3.three µm, as inferred from transmittance measurements utilizing crystal samples of a few mm thickness.
BBO crystals needs to be managed with treatment to prevent scratching or detrimental their surfaces. They should be saved inside of a dry, amazing spot and held far from immediate daylight. Typical cleansing by using a tender fabric or air blower is recommended to maintain their optical effectiveness. When managing BBO crystals, it’s crucial to use gloves to avoid oils with the pores and skin from contaminating the crystal area.
Even if the crystal product or coating is not delicate to drinking water, modest drinking water droplets could concentrate laser radiation much more tightly than below usual Procedure, and therefore injury the crystal materials.
