More information on star product


acousto-optic deflectorsS Eacousto-optic deflectors from CSRayzer Optical Technology

Acousto-optic deflectors are devices which can be used to deflect a laser beam in one direction by a variable angle, controlled by the frequency of an electrical signal. Essentially, such a device is an acousto-optic modulator which is operated with an electrical drive signal of constant power but a variable frequency. CSRayzer provides acousto-optic deflectors for 1 μm and 1.5 μm wavelength, operated with modulation frequencies from 40 MHz to 300 MHz.

acousto-optic frequency shiftersS Eacousto-optic frequency shifters from CSRayzer Optical Technology

An acousto-optic frequency shifter is a device that modifies the frequency of the optical beam. This is a consequence of the Doppler effect; the travelling acoustic wave causing the frequency of the optical beam to be either increased or decreased by an amount equal to the RF carrier frequency. CSRayzer provides frequency shifters for 1 μm or 1.5 μm wavelength, operated with drive frequencies from 40 MHz to 300 MHz.

acousto-optic modulatorsS Eacousto-optic modulators from CSRayzer Optical Technology

CSRayzer offers acousto-optic modulators with fast modulation speed, low insertion loss, high extinction ratio, low power consumption, good temperature stability and high performance reliability. They are a type of optoelectronic product that uses the principle of acousto-optic interaction to perform amplitude modulation and frequency shift processing on lasers. The possible wavelength regions are from the visible to the infrared. It has an all-metal structure design, compact and sturdy hermetic packaging structure, and innovative packaging technology to ensure high reliability and temperature stability. CSRayzer provides free space or fiber-coupled acousto-optic modulators , which are applied for Q-switched fiber lasers, laser Doppler coherent applications, ultrafast laser frequency pulse pickers, linear frequency adjustment, with wavelength range from 300 nm to 2000 nm, and frequency range from 35 MHz to 300 MHz.

acousto-optic Q switchesS Eacousto-optic Q switches from CSRayzer Optical Technology

CSRayzer’s acousto-optic modulators (AOMs) can be used for Q switching lasers. Such an acousto-optic Q switch is placed inside a laser resonator. While the laser is pumped, the RF input of the AOM is switched on, on that the diffraction losses of light circulating in the resonator are high (because the diffracted beams leave the resonator), and lasing is suppressed. When the RF input is suddenly switched off, an intense laser pulse is generated.

erbium-doped fiber amplifiersS E

CSRayzer offers erbium-doped fiber amplifier modules, which are suitable for multi-channel operation in the C band, L band or C+L bands. Models with polarization-maintaining fiber or for pulse amplification are also available.

Faraday isolatorsS EFaraday isolators from CSRayzer Optical Technology

CSRayzer offers many kinds of optical isolators. The free space isolator is based on the optical rotator plus polarizing and analyzer prisms to realize the function of light forward conduction and reverse isolation. It is availabe with different clear aperture sizes, including diameters of 3, 5, 6, 7, 8 and 10 mm. The operation wavelength can be customized. Typical working wavelengths include 800/920/1030/1064/1550 nm, etc., with wide adaptability. Using high-power resistant TGG crystal and Glan laser prism, the optical pulse damage threshold can reach 10 J/cm². The prism is designed with double escape windows.

Faraday rotator mirrorsSFaraday rotator mirrors from CSRayzer Optical Technology

CSRAYZER offers Faraday rotator mirror, which takes the output beam from a single-mode fiber and rotates the polarization by 90° before sending it back through the same fiber. It is used for eliminating polarization-induced fluctuations in fiber interferometers, Brillouin amplifiers, fiber lasers, fiber sensors, and fiber optic antenna remote systems. It has excellent optical performance, an ultra-small package size, high environmental adaptability and reliability.
