The exceptional angle is dependent upon the type of nonlinear method, the wavelength, as well as the crystal thickness. Other solutions for achieving phase-matching in LBO nonlinear crystals incorporate temperature tuning and quasi-section matching.
LBO nonlinear crystals have exceptional Actual physical Attributes, for example significant thermal balance, high destruction threshold, and vast transparency assortment. The thermal conductivity of LBO is relatively low compared to other nonlinear crystals, which makes it additional vulnerable to thermal effects.
We offer precision oven and temperature controller to keep up LBO crystals in a preset temperature for noncritical phasematching (NCPM) for SHG and OPO/OPA. Crystals can be pre-installed to the oven free of charge in our manufacturing unit in your benefit.
Notice that even though the nominal depth is down below the nominal destruction threshold, there might be troubles because of fluctuations inside the beam energy or local depth (e.g., if a beam profile has “sizzling places�?, or due to isolated defects in a very crystal, that happen to be a lot more delicate compared to the common crystal materials.
Raman spectroscopy is a powerful strategy for characterizing the vibrational Attributes of LBO nonlinear crystals. Raman spectroscopy entails shining a laser beam onto the crystal and measuring the scattered light-weight at different wavelengths.
The most common utilization of LBO is in short pulse, substantial pulse amount lasers; the higher electricity density the greater. It is additionally extremely like minded for non-crucial period matching (NCPM) for frequency conversion of CW and quasi-CW radiation, at ninety% conversion performance without the need of wander-off.
SHG and THG for middle and significant electric power Nd: lasers at 1064 nm for clinical, industrial and military services purposes
Below you may submit issues and comments. As far as they get approved by the author, they can appear over this paragraph together with the author’s remedy. The creator will make a decision on acceptance dependant on sure standards. In essence, The difficulty need to be of sufficiently broad interest.
Our crystals are Utilized in an array of applications, which includes many styles of nonlinear frequency conversion and electro-optics, and also quantum technological know-how.
This remarkable pairing of options has led towards the prevalent utilization of LBO inside of a multitude of optical techniques, which makes it a veritable superstar on the globe of nonlinear optics. Indeed, in the event you delve into the heart of numerous modern laser methods, you will likely come across an LBO crystal Performing tirelessly, changing and manipulating mild by using a standard of effectiveness and balance that is actually awe-inspiring.
LBO is section matchable for that SHG and THG of Nd:YAG get more info and Nd:YLF lasers, making use of both type I or variety II conversation. For the SHG at space temperature, form I stage matching is often attained and it has the most effective SHG coefficient inside the principal XY and XZ planes in a large wavelength vary from 551 nm to about 3000 nm.
The Czochralski method permits the manufacture of massive LBO crystals with outstanding crystal good quality and minimal defect density. Even so, the method is pretty gradual and calls for mindful control of the temperature, rotation, and pulling amount to keep up uniform growth.
Characterization approaches are essential for knowledge the properties and optimizing the functionality of LBO nonlinear crystals in several purposes.
By analyzing the emitted mild, the luminescent Houses and defects of your crystal is often identified.
