LBO nonlinear crystals have outstanding Bodily Attributes, like high thermal stability, high injury threshold, and broad transparency array. The thermal conductivity of LBO is relatively minimal as compared to other nonlinear crystals, which makes it much more vulnerable to thermal outcomes.
Also, it may be remarkably appealing to work with a crystal material which may be critically section-matched at room temperature mainly because noncritical period matching typically includes the Procedure with the crystal within a temperature-stabilized crystal oven. Even so, the feasibility of crucial stage matching could be specified just for adequately higher peak powers.
By analyzing the scattered light, the vibrational modes and frequencies on the crystal is usually decided.
A lot of the normal nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the basic laser radiation can be found from inventory. Buyer-specific dimensions and AR coatings may also be presented at aggressive rates.
The selection of the most suitable crystal materials for the offered software is often considerably from trivial; it really should entail the thing to consider of numerous aspects. By way of example, a substantial nonlinearity for frequency conversion of ultrashort pulses isn't going to enable In the event the conversation length is strongly limited by a large team velocity mismatch plus the minimal harm threshold restrictions the applicable optical intensities.
EKSMA Optics employs cookies to provide you with the greatest purchasing experience. In case you go on to make use of our companies, we will assume that you choose to conform to using this sort of cookies.
Too much optical intensities all through operation could instantaneously harm a crystal. However, nonlinear crystals typically have to be operated not considerably from their optical destruction threshold to obtain a adequately superior conversion performance. This means a trade-off amongst conversion efficiency and crystal lifetime.
Also, LBO Crystals boast a sizable nonlinear coefficient. This trait is significant in nonlinear optical procedures for example frequency doubling, exactly where it facilitates effective conversion from the incident light-weight to a distinct frequency.
Non-linear Optical (NLO) crystals present an enormously flexible Alternative for creating new wavelengths from existing, off-the-shelf laser sources. The optical wavelength spectrum is used by a sizable and frequently increasing variety of apps, from production of medical lasers, get more info quantum networking & computing by to environmental sensing along with lots of Other folks.
LBO is section matchable for that SHG and THG of Nd:YAG and Nd:YLF lasers, making use of both variety I or form II interaction. With the SHG at place temperature, type I stage matching is often reached and has the most efficient SHG coefficient during the principal XY and XZ planes in a wide wavelength range between 551 nm to about 3000 nm.
They are able to have excellent beam top quality to the lasers that they substitute for, while executing in hostile environments with no less than routine maintenance.
) to blow off dust and various free contaminants first. If a dry nitrogen line is available during the lab, an air gun can be employed to blow away dust particles. Blow off the surface gently. Do not blow off the crystal by itself from the hand!
Crystal growth is an important stage from the production of high-good quality LBO nonlinear crystals. The choice of crystal advancement approach can significantly effects the crystal excellent, defect density, and optical Homes from the ensuing crystal.
