The knowing and software of these strategies are vital for the development and optimization of varied nonlinear optical devices and apps.
You must think about the wavelength and electricity of your respective laser source and choose a crystal that is definitely transparent within the provided wavelength and might face up to the laser electric power. Last of all, other variables including the thermal steadiness, optical homogeneity, and nonlinear optical coefficient with the crystal also must be considered.
the chemical sturdiness; e.g., some crystal components are hygroscopic, Other folks undergo chemical alterations when heated inside a vacuum chamber for application of the dielectric coating
By analyzing the scattered gentle, the vibrational modes and frequencies of your crystal could be identified.
linear absorption, that may trigger heating at significant optical energy ranges, so which the section matching is disturbed, and thermal lensing may well happen
The characterization of LBO nonlinear crystals is essential for understanding their Houses and optimizing their effectiveness in several programs. This chapter discusses different characterization approaches employed for LBO nonlinear crystals.
Crystals for NCPM at an elavated temperature might be premounted in an oven with precision controller. Crystals applied at ~ twenty - fifty oC will also be premounted in a compatible water-cooled or TEC (ThermoElectric Cooler) cooled mount on request.
LBO Crystals show significant thermal balance and go on click here to function effectively in excess of a large temperature variety. This broad array permits adaptable system style and design and ensures that the crystal efficiency will not be compromised, even underneath fluctuating temperature disorders.
In many circumstances, a nonlinear crystal used for nonlinear frequency conversion has a really extended lifetime, which is longer than that of The complete laser system. The crystal materials is essentially not modified all through operation. Nevertheless, a reduced crystal life time can arise less than numerous situations:
Borates such as LBO and BBO also get the job done perfectly 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, applying possibly form I or variety II interaction. For the SHG at home temperature, form I stage matching is often achieved and has the maximum helpful SHG coefficient from the principal XY and XZ planes in a wide wavelength range between 551 nm to about 3000 nm.
LBO features a lower susceptibility to moisture. Buyers are advised to provide dry conditions for equally the use and preservation of LBO.
g. in the form of “gray tracking�? These types of phenomena are especially widespread for Procedure with ultraviolet light. Note that a gradual degradation may also direct into prompt catastrophic damage by way of extreme heat generation.
In sum, the exclusive blend of performance and longevity that LBO Crystals offer you set them aside on earth of nonlinear optics.
