Ar coating

Imagine looking at a piece of glass. When light interacts with the surface of the glass, a portion of the light is reflected back, creating unwanted reflections that can distort or obstruct the view. The intensity of these reflections can vary depending on factors like the angle of incidence and the refractive indices of the materials involved.

Early on, TeraXion recognized the emerging importance of ultrafast lasers also known as ultrashort pulse lasers for industrial and medical applications. To address this need, TeraXion has developed a line of high-quality pulse stretchers and dispersion management reflectors that are robust, cost-effective, and versatile.

Most industrial pico- and femtosecond laser systems utilize mode-locking to generate ultrashort pulses. The challenge with mode-locking is that the process requires a broad frequency band, but all the different wavelengths must maintain a defined phase relation as the pulse propagates within the cavity. TeraXion’s all-fiber dispersion-management reflectors provide precise control over the chromatic dispersion within the laser cavity, ensuring stable and short pulses.

anti-reflective coating是什么

Get the most out of your glasses by choosing lenses with an anti-reflection coating. It's not just your glasses that can be coated with this in order to help your eyes… you can also add it to screens, and cameras! Here’s what an anti-reflection (AR) coating is and how it works…

Anti-reflection coatings work by manipulating the behaviour of light as it transitions from one medium (such as air) to another (such as glass). This transition causes a portion of the incident light to be reflected at the interface due to the difference in refractive indices. The goal of the AR coating is to minimise these reflections by carefully engineering the thickness and refractive index of the coating material.

Ultrafast fiber lasers are also increasingly being used in new and emerging applications such as biomedical microscopy and imaging, spectroscopy and for advanced scientific research.

Ultrashort pulse amplification is challenging because even low-energy pulses exhibit sufficient peak power to damage the amplifier. Stretching the pulse over time reduces its peak power and allows for optimal amplification without distortion—further stretching enables higher amplification. Recompressing the pulse following amplification returns it to its original ultrashort duration with significantly increased peak power—often in the gigawatt range. TeraXion’s line of ultrafast laser components maximizes both performance and cost effectiveness. These products include fixed and tunable pulse stretchers as well as stretcher+compressor matched pairs.

anti-reflectioncoating

An anti-reflection (AR) coating is a thin layer of material applied to the surface of optical components, such as lenses, glass panels, and displays, with the primary purpose of minimising the reflection of light. This ingenious technology has become an integral part of various devices, enhancing visual clarity.

Ultrafast lasers are crucial for precise material processing in electronics, automotive parts, and medical components, offering high peak power and precise cold ablation machining capabilities. Their design prioritizes quality components to ensure cost-effectiveness and robust performance in 24/7 manufacturing environments. Chirped-pulse amplification boosts pulse energies to meet advanced manufacturing needs beyond what mode-locked oscillators alone can provide.

Terahertz radiation possesses unique properties, such as the ability to penetrate various non-conductive materials like plastics, fabrics, and biological tissues, without causing ionization.  The success of deploying THz technologies heavily depends on the availability of compact, efficient, and affordable THz sources. Femtosecond lasers are crucial tools for generating terahertz (THz) radiation due to their ability to produce extremely short, high-intensity pulses.

Multiphoton microscopy (MPM) is a powerful imaging technique widely used in biological and biomedical research. Unlike traditional fluorescence microscopy, which uses single-photon excitation, MPM employs multiple photons to excite a fluorescent molecule. One of the biggest challenges to the widespread adoption of multiphoton microscopy is finding a suitable light source for efficient fluorophore excitation.  To reach the high peak power needed for nonlinear optical processes, femtosecond mode-locked lasers are used.
