They can be utilized for frequency doubling invisible just one-micron light-weight into 532nm seen environmentally friendly light-weight, an application which has Earlier belonged to KTP crystals.
You must take into account the wavelength and electric power of one's laser source and choose a crystal that is clear within the supplied wavelength and may withstand the laser ability. Last of all, other factors including the thermal security, optical homogeneity, and nonlinear optical coefficient in the crystal also need to be thought of.
Filters under or the shape at the bottom can be employed to aid solution look for or make additional inquiries.
Notice that whether or not the nominal intensity is under the nominal problems threshold, there may be difficulties on account of fluctuations from the beam energy or local depth (e.g., if a beam profile has “sizzling places�?, or due to isolated defects within a crystal, which are a lot more delicate as opposed to frequent crystal materials.
linear absorption, which can trigger heating at large optical electricity degrees, so that the period matching is disturbed, and thermal lensing could arise
The optimum crystal orientation for optimum SHG effectiveness in LBO nonlinear crystals is the kind I phase-matching course, which corresponds into a ninety-degree angle in between the enter and output polarizations.
X-ray diffraction is a robust strategy for analyzing the crystal framework and orientation of LBO nonlinear crystals.
GWU-Lasertechnik presents all normal nonlinear crystals like LBO, BBO and KTP with a wide selection of technical specs. Beside the very well-set up products, ground breaking crystals like CLBO or BiBO with exceptional Attributes for e. g. deep-UV generation or significant-electrical power ultrashort pulse lasers are offered. Despite if person items for R & D functions are expected or Price-successful figures in compact, medium or big batches with in-time shipping for the manufacturing line are wanted: GWU’s focused services helps you to locate the very best Main components to your application.
Sort II NCPM OPO pumped by a XeCl excimer laser at 308nm has achieved sixteen.5% conversion performance, and reasonable tunable wavelength ranges could be obtained with unique pumping sources and temperature tuning.
General, the characterization methods talked over With this chapter deliver precious insights to the techniques used for the characterization of LBO nonlinear crystals.
LBO is stage matchable for your SHG and THG of Nd:YAG and Nd:YLF lasers, applying both style I or sort II conversation. For your SHG at home temperature, sort I period matching may be achieved and it has the utmost helpful SHG coefficient inside the principal XY and XZ planes in a broad wavelength range from 551 nm to about 3000 nm.
In this article, they transform gentle at just one frequency into gentle at two times the frequency, therefore halving the wavelength. This method is important in generating lasers of different colors, extending their use to a wide variety of applications. This includes but isn’t restricted to professional medical treatments, laser Exhibit devices, optical knowledge storage, and also Superior study.
The commonest system for accomplishing period-matching in LBO nonlinear crystals is angle tuning, wherever the crystal is rotated to discover the ideal angle that satisfies the stage-matching problem.
They exhibit very good homogeneity about significant volumes and possess a high harm threshold, but are hygroscopic LBO Crystal and have a minimal nonlinearity.
