The being familiar with and software of those approaches are essential for the development and optimization of varied nonlinear optical units and applications.
In this technique, a little seed crystal is placed on major of a supersaturated Resolution from the starting off components, usually Li2O and B2O3, in a progress vessel. The answer is then slowly but surely cooled to allow for crystal progress in the seed crystal.
But LBO has improved transparency, fewer flaws, and will not experience gray tracking. The result is greater ability and life time functionality. It is usually less costly than hydrothermal KTP, so it's got begun to interchange KTP in the more demanding applications.
The flux technique allows for the production of substantial LBO crystals with very low defect density and higher optical good quality. The usage of a flux may also help to cut back impurities and defects from the crystal, leading to enhanced crystal quality.
The superb optical homogeneity and lack of inclusions in GAMDAN material indicate wonderful undistorted wavefront output from a product. LBO has an exceptionally superior inside problems threshold because of its low absorption. That home also avoids beam distortion from thermal growth.
The characterization of LBO nonlinear crystals is important for knowledge their Homes and optimizing their efficiency in a variety of applications. This chapter discusses the different characterization strategies utilized for LBO nonlinear crystals.
LBO can get to equally temperature NCPM and spectral NCPM (with an exceptionally extensive spectral bandwidth) at 1300 nm. That is favorable for that SHG of quite broadband or ultrafast pulses at ~ 1300 nm.
Be sure to use "Add to Cart" to place the exciting solutions from the browsing cart. Look into with on-line payment or check with us for the prices/availability by means of the shopping cart.
Type II NCPM OPO pumped by a XeCl excimer laser click here at 308nm has reached 16.five% conversion effectiveness, and reasonable tunable wavelength ranges can be attained with distinct pumping resources and temperature tuning.
Borates for example LBO and BBO also get the job done properly in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
LBO is section matchable for that SHG and THG of Nd:YAG and Nd:YLF lasers, using both style I or sort II conversation. For your SHG at space temperature, style I stage matching could be arrived at and has the utmost powerful SHG coefficient within the principal XY and XZ planes in a wide wavelength range between 551 nm to about 3000 nm.
Many different Attributes of a nonlinear crystal may be crucial for an application e.g. in nonlinear frequency conversion:
flux-developed KTP and RTP with its large nonlinearity, also in variants with high grey tracking resistance
The TSSG process permits the creation of higher-top quality LBO crystals with very low defect density and superb optical Attributes. The use of a seed crystal allows to regulate the crystal orientation and defect density, leading to improved crystal quality.
