Pockels cells
Pockels Cells are important electro-optic device which exploit the pockels effect. Applying a constant or varying voltage (electric field) on Electro-Optic Crystals can cause the crystal birefringence to change linearly.
BBO Crystals for EO Applications
Beta-Barium Borate ( BBO) crystal is an excellent electro-optic crystal for high power applications at the wavelength range from 200nm to 2,500nm. It could be used as the EO Q-switching crystals, Beta BBO crystals or beta barium borate crystals exhibit significant advantages over other materials in terms of laser power handling abilities,high damage threshold temperature stability, and substantial freedom from piezoelectric ringing.
Introduction to Waveplates and Retarders
It is crucial for buyers to discriminate the differences between the various types of Waveplates and Retarders, here is a general, simple and approachable introduction about waveplates and retarders, to help you understand better the differences and traits of each type of them.
Super Achromatic Waveplates
Shalom EO recently joined the development of Super Achromatic Waveplates. Unlike conventional achromatic waveplates, super achromatic waveplates consist of six waveplates aligned together, three made from quartz (Crystalline SiO2) and three made from magnesium fluoride (MgF2). With an increased number of composing waveplates, this design minimizes the fluctuations of retardation and substantially broadens the application spectrum from the UV to the NIR.
Introduction to Acousto-Optic Crystals
Acousto-Optic Crystals are crystals that exhibits photoelastic effects, where mechanical waves stimulate elastic strains in the crystals, acting as periodic phase gratings and alters the refractive indices, leading to changes in the optical properties. The AO crystals are excellent candidates for to be processed into the acouto-optic medium of the Acousto-Optic Modulators (AOM) including AO Q-switch, Acousto-Optic Deflectors (AOD), Acousto-Optic Frequency Shifter (AOFS), and Acousto-Optic Tunable Filters (AOTF), etc.
Double Surface Super-Polishing Technique
Hangzhou Shalom EO has successfully developed a double surface polishing method for processing high precision optical windows or substrates, made from N-BK7 and UV Fused Silica, which are one of the most crucial components for Femto-line laser systems.
What is Second Harmonic Generation (SHG)
The application of the Second Harmonic Generation (SHG) technique is boosting currently. The technique has been utilized extensively as a measure to obtain laser light with short wavelengths which are not directly procurable, for example, 532nm green output for Nd: YAG lasers, or ultra-violet lights with further SHG. The equations and definitions of second harmonic generation are given in this article to deliver an elaborate theoretical explanation about shg.
Optical Basics: What is FOV (Field of View)
