Customized coatings is often placed on the crystal surfaces to improve their efficiency at specific wavelengths or to shield the crystal from environmental variables. However, it’s crucial to Observe that any customization need to be completed diligently to stay away from degrading the crystal’s optical properties.

A2: Of course, prolonged publicity to humidity can degrade the optical performance of BBO crystals. Humidity can result in h2o absorption to the crystal area, which often can impact its optical Homes.

Thorlabs offers a large choice of optics optimized for use with femtosecond and picosecond laser pulses. Be sure to see below To learn more.

Now Examine the utmost energy density to that which can be specified given that the LIDT with the optic. If your optic was examined at a wavelength apart from your working wavelength, the destruction threshold needs to be scaled properly [3].

BBO is of particular relevance in the obvious and far UV. A wide variety of phase-matching apps are achievable, including the adhering to:

Phase matching drastically enhances the conversion efficiency and can be needed to obtain ample frequency-doubled light-weight for programs, but next harmonic era (SHG) will manifest even though stage matching isn't performed. The influence of section matching over the output depth of SHG mild (I2ω) is illustrated in Figure 16.

This produce-up will describe how we produce significant-top quality BBO crystals at our organization. We will even review some positive aspects and troubles of employing BBO crystals for regularity conversion.

Specified these programs, it’s apparent why BBO, with its inherent ability to effectively develop the 266nm wavelength, is so highly prized. The crystal’s special nonlinear optical Qualities enable the conversion of other wavelengths into the coveted 266nm gentle, making certain that researchers and industries have access to this critical Software.

It’s crucial that you avoid working with abrasive components or powerful solvents, as these can scratch or if not injury the crystal’s area. Normal cleaning may help maintain the crystal’s optical overall performance and prolong its lifespan.

Taken alongside one another, these varied apps underscore the huge price BBO crystals read more convey to many sectors. Through its unparalleled 266nm generation, the BBO crystal is not just a Instrument but a catalyst, propelling developments throughout diverse fields.

Substantial nonlinear coefficients: BBO crystals have considerable nonlinear coefficients that make economical frequency conversion procedures with low input power requires attainable.

As will likely be discussed below, You will find there's focusing numerical aperture (NA) limitation to the SHG period-matching course of action precisely analogous into the spectral period matching limitation talked over during the past area (

Because of its outstanding Qualities BBO crystal features a quantity of benefits for various programs, like NOPA with fsec pulses, harmonics technology (as many as fifth) of Nd:YAG and Nd:YLF lasers, frequency doubling or tripling of femtosecond Ti:Sapphire and dye lasers, OPO at Variety one and sort 2 section-matching, E/O switching for Pockels cells and a number of other.
