LBO is a superb NLO crystal for OPOs and OPAs which has a commonly tunable wavelength selection and high powers. The distinctive Attributes of form I and type II phase matching along with the NCPM depart an enormous space while in the exploration and purposes of LBO's OPO and OPA.
Nevertheless, This may be mitigated by using suitable cooling approaches for the duration of crystal advancement and machine operation.
These qualities minimize the alignment sensitivity on the optical program and be certain better beam propagation. The considerably less stringent alignment prerequisites and greater beam excellent conferred by these functions frequently idea the size in favor of LBO Crystals more than other nonlinear optical crystals.
GWU-Lasertechnik has greater than thirty many years of practical experience in distributing laser crystals. Select GWU to benefit from our extensive understanding As well as in-area experience!
Dennis is surely an engineer with in excess of forty five several years of working experience in fabrication, testing, and content evaluation for high precision optics, with substantial fingers-on expertise. A lot more around the author are available below.
The most typical utilization of LBO is Briefly pulse, significant pulse rate lasers; the higher electricity density the greater. It is also very well matched for non-crucial period matching (NCPM) for frequency click here conversion of CW and quasi-CW radiation, at ninety% conversion performance without walk-off.
LBO can reach the two temperature NCPM and spectral NCPM (with an extremely wide spectral bandwidth) at 1300 nm. This is favorable for that SHG of really broadband or ultrafast pulses at ~ 1300 nm.
Whether it’s a small-temperature scientific experiment or maybe a large-temperature industrial procedure, you can rely on LBO Crystals to deliver regular effectiveness. Their capacity to take care of their nonlinear optical Homes across a large temperature vary even more augments their flexibility.
In the situation of ultrashort pulses the significant group velocity mismatch enforces the usage of a shorter crystal, which requires substantial optical intensities for a presented conversion performance.
Just about the most common apps of LBO nonlinear crystals is frequency doubling, in which the fundamental frequency of a laser beam is doubled to supply a higher frequency output.
LBO is period matchable for the SHG and THG of Nd:YAG and Nd:YLF lasers, employing possibly style I or type II interaction. To the SHG at home temperature, type I section matching can be reached and it has the utmost productive SHG coefficient in the principal XY and XZ planes in a large wavelength vary from 551 nm to about 3000 nm.
In spectroscopy, OPO is utilized to make tunable light resources for several programs, such as chemical Assessment and content characterization. In metrology, OPO is utilized to deliver frequency combs for specific frequency measurements.
PL spectroscopy can be used to determine impurities and defects in LBO nonlinear crystals which can have an impact on their overall performance in a variety of apps. PL spectroscopy may also be employed to find out the crystal quality and homogeneity.
By examining the emitted gentle, the luminescent Houses and defects of your crystal may be decided.
