ALS-VIS High power, low noise CW frequency-doubled amplifier

Lasers are used to realize most of the quantum systems used for quantum computing and simulation. Lasers are utilized to prepare quantum states, to realize quantum gates, and to read out qubits. In addition, lasers are used to link different quantum systems (e.g. to connect quantum computers or quantum computing subunits), a major task of quantum communication. Tunable diode lasers, fiber amplifiers, optical frequency combs, and wavelength meters, ideally combined in laser rack systems as complete solutions, are the most important products. 

Holography has evolved from an artistic curiosity into a cornerstone technology for next-generation optical systems. From augmented reality (AR) displays and automotive lighting to precision metrology, data storage, and optical security, holography today enables engineers and designers to shape, direct, and control light with unprecedented precision.

Laser-based metrology and inspection have become indispensable tools for shrinking feature sizes, more and thinner layers, as well as increasing chip and package areas. 

Direct writing lithography is applied across multiple fields that require precise patterning at micron or nanometer scales, particularly where flexibility or customization is important.

Argon gas lasers have a long legacy for emission wavelengths like 488 nm or 515 nm. But they come with a low optical-electrical efficiency (< 0.1 %), bulky water cooling, frequent argon tube replacements, and are prone to misalign. Today, cost-efficient and long-lived fiber laser technology replaces them. 

TOPTICA's products are widely and successfully used for scientific applications in fundamental quantum technology. In these fields quantum physics, quantum optics, atom optics, photonics, statistical physics and related fields are investigated in order to understand the basics of quantum technology.
