The TSSG process is a comparatively new technique which has acquired attractiveness for its capability to make superior-top quality crystals with reduced defect density.
You should evaluate the wavelength and power of your laser supply and decide on a crystal that may be transparent in the specified wavelength and may face up to the laser electricity. Lastly, other variables like the thermal steadiness, optical homogeneity, and nonlinear optical coefficient of your crystal also should be deemed.
Also, it can be highly fascinating to employ a crystal product which may be critically stage-matched at place temperature for the reason that noncritical period matching typically requires the Procedure in the crystal in a temperature-stabilized crystal oven. However, the feasibility of vital stage matching may be supplied only for sufficiently high peak powers.
The flux approach permits the manufacture of large LBO crystals with small defect density and higher optical good quality. The use of a flux will help to cut back impurities and defects in the crystal, leading to improved crystal high quality.
Many of the regular nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the basic laser radiation are offered from stock. Client-unique Proportions and AR coatings can also be made available at aggressive prices.
LBO LBO Crystal crystal (lithium triborate) is one of the most made use of nonlinear crystal for harmonics generation for brief and extended pulse apps. As a consequence of it’s somewhat small walkoff angle very long crystals might be made use of what enables to obtain higher conversion performance.
A hybrid technique that mixes some great benefits of the Czochralski and TSSG approaches has also been produced to the creation of LBO nonlinear crystals. In this process, a small seed crystal is to start with grown using the TSSG method, and then the crystal is connected to the rod and utilised to be a seed to the Czochralski technique. The ensuing crystal is a hybrid crystal by using a low defect density and superior optical quality.
LBO is the primary choice for creating doubler or tripler for lasers like Nd:YAG where large electrical power density, higher steadiness, and very long time operation are demanded.
In the case of ultrashort pulses the high team velocity mismatch enforces using a shorter crystal, which involves significant optical intensities for just a specified conversion performance.
Borates like LBO and BBO also work well in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
In spectroscopy, OPA is utilized to crank out tunable gentle resources for different apps, for instance chemical analysis and material characterization. In telecommunications, OPA is utilized to amplify and change signals in optical interaction units.
g. twenty μm. The team velocity mismatch within the thicker substrate content might not subject, as the nonlinear conversation takes location only in the thin crystal. The substrate only serves to mechanically stabilize The skinny nonlinear crystal.
Optical crystals can exhibit different types of optical nonlinearities, which can be utilized in various ways:
By examining the emitted light, the luminescent Homes and defects of your crystal may be decided.
