Optical lenses can be made in many shapes and may be comprised of a single element or form constituent parts of a multi-element compound lens system. They are used to focus light and images, produce magnification, correct optical aberrations and for projection, mainly controlling the focus or divergence light used in instrumentation, microscopy and laser applications.

Basically all Pockels cell drivers are made based on solid-state electronic technology, using high voltage transistors such as MOSFETs. Multiple high voltage transistors may have to be stacked, taking care to achieve an even distribution of voltage across those. Instead of using some heavily isolated floating gate drive circuitry for the different transistors, one may use certain advanced ideas such as implementing so-called avalanche switch stacks involving avalanche diodes and/or avalanche bipolar transistors.Device lifetimes can be very long, provided that properly engineered

Thin film polarizers are based on interference within a dielectric optical thin-film coating on a thin glass substrate. They are made from composed materials which include a polarizing film, an inner protective film, a pressure-sensitive adhesive layer, and an outer protective film. Thin film polarizers are used for polarization separation, that's to say to change un-polarized beam into linear polarized beam.

Polarizer is a kind of optical filter where the light transmission depends strongly on the polarization state. Normally, light with linear polarization in a certain direction is passed, and light polarized in an orthogonal direction is either absorbed or propagated to a different direction.For other directions of linear polarization with an angle θ against the“passing”direction, the transmission exhibits a cos2 θ dependence. That can be understood by considering that linear polarization state as a linear superposition of the "passing”and the“blocked”state.Most polarizers act

When classified by coatings, Optical Mirrors consist of dielectric mirrors and metallic mirrors. Dielectric mirror is an optical mirror made of thin layers of dielectric coating layers deposited on an optical substrate (UVFS or BK7). WISOPTIC offer dielectric laser mirrors for laser lines, for narrowband or broadband wavelength ranges covering spectrum from UV to IR. Metallic mirrors are coated with protected gold, silver, or aluminum. Metallic mirrors are widely used due to a moderate level of reflection over a very broad spectral range.

A right angle prism is an optical prism designed to deviate light by 90° or 180°, depending on the orientation of the prism and the face through which light enters. The joining edges and faces are perpendicular to the base faces, and all joining faces are rectangular. They are often  preferable to plane mirrors, because they are easier to mount and align.

A corner cube (or cube corner), also known as a retroreflector, is an optical component with the unique ability to return an incoming beam of light directly towards its point of origin regardless of the beam's angle of entry. This property makes this prism type ideal for a wide variety of applications, such as laser resonator cavities, land surveying, ground based range-finding, satellite communications and space vehicle docking.Wisoptic offer a wide variety of retroreflectors at competitive prices and lead times, and are able to accommodate the most demanding requirements.

BBO(Beta-Barium Borate, β-BaB2O4)based Pockels cells operate from approximately 0.2 - 1.65 µm and are not subject to tracking degradation. BBO exhibits low piezoelectric response, good thermal stability, and low absorption. Due to the low piezoelectric coupling coefficients of BBO, BBO Pockels cells function at repetition rates of hundreds of kilohertz.

Optical filters are used to selectively transmit or reject a wavelength or range of wavelengths. Their applications include fluorescence microscopy, spectroscopy, clinical chemistry, machine vision inspection, etc. Optical filters are widely used in light system of life science, imaging, industrial, or defense industries. For example, Bandpass interference filters are designed to transmit a portion of the spectrum, while rejecting all other wavelengths. Notch filters reject a portion of the spectrum, while transmitting all other wavelengths.

Experimental SetupIn order to obtain a 266 nm deep ultraviolet laser with high efficiency and stable operation, this paper built an all-solid-state 266 nm deep ultraviolet laser generation device as shown in Figure 1, which consists of a cavity-dumped all-solid-state Nd:YVO4 laser, a double-frequency system, and a quadruple-frequency system.Fig.
Introduction 532nm solid-state lasers are widely used in industry and medicine. In the field of scientific research, continuous, high-stability 532nm green light and kilohertz, high-energy nanosecond 532nm laser are the most ideal pump source solutions for titanium sapphire oscillators and amplifiers respectively. The basic route is to use an 808nm/880nm semiconductor laser as the pump source, generate a 1064nm laser in an Nd:YVO4 or Nd:YAG crystal, and then perform frequency doubling (SHG) through a frequency doubling crystal to generate a continuous or pulsed 532nm laser.
03 Experimental results and analysisBy optimizing the cavity length parameters of Nd:YVO4 (www.wisoptic.com) laser under high-power pump injection, a 1064 nm high peak power narrow pulse laser output with an average power of 26 W, a repetition frequency of 20 kHz, and a single pulse width of 5 ns was obtained when the 888 nm pump light power was 65 W; after the 1064 nm fundamental frequency infrared light was doubled by the LBO crystal, a 532 nm laser with a maximum power of 16 W was finally obtained, and the infrared to green light conversion efficiency reached 61.5%.
In 1962, the American scientist McClung F J reported for the first time that the silver mirror of the ruby laser resonator had hole burning damage, which was the first public report on the laser damage of optical components. The subsequent invention of Q-switching technology and mode-locking technology increased the peak power of laser pulses by several orders of magnitude. The problem of laser damage runs through and affects the design and operation of lasers, and promotes the development of optical materials and optical component manufacturing technologies.

Experimental Result and Analysis4.2 Temperature robustness comparison between CPPLN and LBOAs a relatively new nonlinear optical material, CPPLN has a high nonlinear coefficient and a large gain bandwidth. In the foreseeable future, it will have more applications in the fields of industry and medicine. With the increasing demand for polarized crystal materials such as PPLN and CPPLN, the electric field polarization technology of crystals will also have further breakthroughs, and the processing accuracy of polarized crystals will continue to improve.
2.2 Fabrication of lithium tantalate crystal with near stoichiometric ratioThe preparation of near-stoichiometric lithium tantalate (NSLT) crystals is difficult. The current methods mainly include: the double crucible method, the flux pulling method, the float zone method and the gas phase exchange equilibrium method. 2.2.1 The double crucible methodIn the double crucible method, the melt material needs to be continuously added to the crucible during the crystal preparation process to keep the melt composition unchanged.
