One/Two-dimensional High-speed Acousto-optic Deflectors

One/Two-dimensional High-speed Acousto-optic Deflectors

Acousto-optic deflectors (AODs) are devices that utilize the acousto-optic effect to control and manipulate light beams, particularly in laser systems.By varying the RF signal applied to the transducer, the angle of deflection can be precisely controlled, enabling rapid deflection of a laser beam in one or two dimensions.This technology enables real-time, precise control in applications like ultra fine laser machining,microscopy, holography, and optical trapping due to its swift response to RF signals and no mechanical movement.

10.6um AOM /Large Aperture AOM/300MHz AOM

10.6um AOM /Large Aperture AOM/300MHz AOM

"The selection of crystal materials and structural design constitute multiple types of acousto-optic modulators(AOMs). Like, high-quality infrared acousto-optic crystals can be used in CO2 laser systems to develop 10.6um AOMs with high diffraction efficiency. Large aperture AOM with high damage thresholds can be suitable for high-power ultrafast laser systems.

The 300M fiber-coupled acousto-optic modulator(FCAOM) couples the laser beam into and out of the modulator using fiber components to ensure high extinction ratio, low insertion loss, and excellent stability.The compact and rugged hermetic design makes it particularly suitable for applications requiring long-distance signal manipulation, or integration into complex optical systems.

Thin-disk Yb:YAG & Yb Doped Laser Crystals for Ultra-short Pulse Lasers

Thin-disk Yb:YAG & Yb Doped Laser Crystals for Ultra-short Pulse Lasers

Yb doping ultra-fast laser crystals such as Yb:CALGO, Yb:CaF2, Yb:KGW, Yb:YAG (thin-disk) are excellent gain media for generating ultrashort high-power pulses. This series of crystals have the advantages of large absorption cross-section at 980nm band, high thermal conductivity and wide emission line width, etc., which not only make it possible to effectively utilize diode laser (LD) pumping, but also become the preferred material for high power diode pumping system. Laser amplifiers with high optical-to-optical conversion efficiencies are one of the important potential applications for semiconductor-pumped femtosecond (fs) lasers and amplifiers.

R>99.999% Ultra-high Reflectivity Mirrors

R>99.999% Ultra-high Reflectivity Mirrors

The 1550 nm band laser is becoming one of the common optical detection bands used in commercially available high-precision greenhouse gas analyzers. Ultra-high reflectivity mirrors are the core components of high-precision greenhouse gas analyzers using optical cavity decay spectroscopy (CRDS). Our company has developed and launched a high quality all-dielectric optical film with a reflectivity of 99.999% or more in the 1550 nm band, which is characterized by ultra-smoothness, ultra-low absorption, ultra-low scattering, ultra-smoothness, ultra-low scattering, ultra-low scattering, and ultra-smoothness. Surface quality 0-0 in the center area and optical loss (absorption + scattering) below 6 ppm.

Free-form lenses& Axicons

Free-form lenses& Axicons

High precision is a significant feature of our axicon.We can process the RMSi to be less than 20nm, the current top angle tolerance and vertex circle diameter are within 0.003 degrees and 0.7mm. Based on our processing capabilities,the axicon we produce can create an outstanding beam with a Bessel intensity profile. Free-form surfaces are non-conventional continuous surfaces that do not have an axis of symmetry. free-form surfaces are not rotationally symmetric and cannot be described by simple geometric curves, free-form surfaces are often machined by point contact. The highest level of surface shape we can process is RMS 50nm.
