The crystal axis is c. The Main ray is parallel for the path accustomed to evaluate the tuning angle (θ), which happens to be optimized all through stage matching. Conversion efficiency is optimized for rays parallel into the Main ray and worse for rays at larger angles (ψ) on the chief ray.
A2: Sure, extended exposure to humidity can degrade the optical efficiency of BBO crystals. Humidity may lead to water absorption about the crystal floor, which might have an affect on its optical Homes.
In an effort to use the specified CW damage threshold of the optic, it is necessary to learn the next:
Even so, to fully make use of the possible of BBO crystals, it can be critical to understand their Attributes and how to deal with and retail store them appropriately. These crystals have to have watchful handling to prevent harm to their surfaces and should be saved inside a dry, great put to take care of their optical functionality.
BBO crystals may be cleaned utilizing a soft cloth or air blower. For stubborn stains, a mild detergent or isopropyl Alcoholic beverages can be used. It’s crucial that you stay away from employing abrasive elements that would scratch the crystal’s surface area. When cleaning BBO crystals, it’s imperative that you use a gentle, circular movement to stay away from scratching the area.
Please note that We now have a buffer crafted between the required injury thresholds online and the checks which We've performed, which accommodates variation concerning batches. On ask for, we can offer particular person exam information and facts in addition to a testing certification.
Bodily, when the basic spectrum is properly in the reference pulse spectrum, the SHG pulse depth profile will be the sq. of the elemental intensity profile, efficiently truncating the length. This circumstance is illustrated in Figure twenty.
The destruction Assessment is going to be performed on an identical optic (customer's optic will not be harmed). Tests could end in additional expenditures or guide instances. Call Tech Help For more info.
BBO crystals need to be managed with care to stay away from scratching or harming their surfaces. They need to be saved within a dry, cool area and saved faraway from direct daylight. Normal cleansing by using a delicate fabric or air blower is recommended to keep up their optical overall performance. When dealing with BBO crystals, it’s crucial that you use gloves to forestall oils within the pores and skin from contaminating the crystal floor.
On top of that, spectroscopy, a method that’s basic in analyzing and understanding the Homes of assorted substances, reaps the benefits get more info of BBO’s capabilities. Spectroscopy relies around the conversation concerning gentle and make any difference to derive insights a couple of substance’s composition, construction, and various Attributes.
The fundamental supply is the dye laser radiation pumped by the next harmonic of the Q-switched Nd: YAG laser. A stroll-off compensated configuration While using the BBO crystal pair has enabled us to understand such a significant conversion effectiveness from the conversation.
For beams by using a high PRF the two the standard and peak powers should be as compared to the equal CW power. Furthermore, for hugely clear elements, There may be minimal to no fall during the LIDT with expanding PRF.
When an input pulse's spectral selection is equal to or narrower than the reference pulse, the created second harmonic pulse has a length that may be shorter by a factor of one/√two and also a spectral width that may be broader by a factor of √two.
In frequency conversion, BBO crystals are accustomed to alter the colour of laser gentle, enabling the production of an array of hues that aren't instantly accessible from readily available laser sources. In electro-optic modulation, They may be applied to manage the intensity, period, polarization, or way of a laser beam.
