If you do not discover the appropriate products and solutions previously mentioned, you might allow us to know your specifications or programs in the shape underneath. Our product sales or specialized staff can get back again to you personally as quickly as possible.
Inertness to Humidity: BIBO crystal is inert to moisture, which suggests it doesn't degrade or reduce its optical Houses when exposed to humidity. This makes BIBO a far more stable and dependable selection for optical programs in a variety of environments.
The vast majority of typical nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the elemental laser radiation can be found from inventory. Consumer-specific dimensions and AR coatings are also available at aggressive charges.
By submitting the knowledge, you give your consent on the likely publication of the inputs on our Site In line with our principles. (Should you later retract your consent, We're going to delete All those inputs.) As your inputs are initially reviewed with the writer, they may be published with a few delay.
Artifex Engineering supplies finished crystal optics for non-linear purposes. Take a look at our product or service website page for more information. We stay up for your inquiry.
Dust and stains on crystal surfaces might cause scattering/reduction of sunshine and can even respond with gentle to break optical surfaces at a significant incident laser electrical power.
The choice with the most suitable crystal substance for a presented application is commonly significantly from trivial; it need to involve the thought of numerous areas. For instance, a significant nonlinearity for frequency conversion of ultrashort pulses does not aid When the conversation duration is strongly confined by a sizable group velocity mismatch plus the reduced hurt threshold limitations the applicable optical intensities.
Scientific study and enhancement: BIBO crystals also Perform an essential position in scientific study and progress. Its superb nonlinear optical performance gives new tools and options for ultrafast phenomenon analysis, robust area physics, biomedical imaging as well as other fields
Although the nonlinear coefficient of KTP crystal is huge, the laser destruction threshold is reduced, that will induce issues such as refractive index improve and transmission loss. BIBO crystal has better laser harm threshold and higher 2nd harmonic conversion performance. Although LBO and B-BBO are the most practical, they are compact in dimension and possess specific hygroscopicity, though BIBO crystals are non-moist and can expand to large measurement. These benefits enable BIBO crystals being extensively employed.
Crystals which happen to be non-critically section-matched in a very crystal oven may perhaps show difficulties if the crystal temperature is adjusted too speedily or also normally. In particular, anti-reflection coatings may be broken on account of diverse thermal expansion coefficients in the included resources.
In several instances, a nonlinear crystal employed for nonlinear frequency conversion has an extremely extensive life span, which is for a longer period than that of The entire laser process. The crystal product is essentially not modified through Procedure. Nonetheless, a reduced crystal life time can come about below a variety of conditions:
The load with the solvent will cause the lens tissue to come back into connection with the crystal floor. Slowly but steadily drag the damp lens tissue across the crystal surface becoming mindful to not raise the lens tissue off in the surface area. Proceed dragging the lens tissue right up until it truly is off with the surface area.
The magnitude with the here efficient nonlinear coefficient depends upon the nonlinear tensor factors and within the utilized period-matching configuration. A substantial nonlinearity is vital significantly If your achievable optical intensities are very low.
High Damage Threshold: BIBO crystal features a significant problems threshold, allowing for it to face up to substantial laser electrical power with out struggling problems. This characteristic tends to make BIBO well suited for use in substantial-power laser methods.
