Helium cadmium (HeCd) lasers have long been a staple in various scientific and industrial applications, prized for their precise wavelengths and stable output. However, recent regulatory changes in the European Union (EU) have impacted their availability, prompting the need for alternatives.
Today, amid the second quantum revolution new sensing schemes offer higher sensitivities and better resolution thanks to the possibility to detect and control individual quantum states in microscopic systems like atoms, quantum dots, or color centers. Emerging quantum sensing techniques could lead to the improvement of sensing technologies ranging from quantum gravitometers and accurate atomic clocks to low-noise quantum-interference microscopy and ultimately find commercial uses in gyroscopes for self-driving cars, or brain-machine interfacing via magnetic-field sensing.
At the heart of quantum computing are qubits, the quantum analogs of classical bits. Unlike classical bits, which can be either 0 or 1, qubits can exist in a superposition of states, embodying both 0 and 1 simultaneously. This property, along with entanglement and quantum interference, enables quantum computers to solve complex problems more efficiently than classical computers.
Cooling atoms to ultralow temperatures has produced a wealth of opportunities in fundamental physics, precision metrology, and quantum science.
On this post we collate some of the Raman spectroscopy terms, along with a short description to help guide through many of the different techniques often used today in the field of Raman spectroscopy.
Multiphoton microscopy has revolutionized biological imaging by allowing high-resolution imaging in 3D without the need for dyes or labels. An important aspect of this technology is the use of very short femtosecond pulses. Read more here!
Ultrafast fiber lasers have revolutionized the field of photonics, offering a range of advantages over traditional lasers. One of the main advantages of using ultrafast femtosecond fiber lasers is the high peak power that they offer, which is a result of their ultra-short pulse duration. Read more here!
In this application note, we discuss the laser characteristics needed for Brillouin spectroscopy and show that this technique can be used to characterize the magnetic properties of ferromagnetic thin films.
In this post, read about what performance improvements can be achieved by using a 405 nm laser compared to longer wavelength lasers that are used more conventionally in Raman experiments.
A Multi-line laser is a single compact laser head with multiple lasers built inside and collimated into a single permanently aligned output beam, thus giving the appearance of a single laser with multiple wavelengths. The multi-line laser is therefore very attractive as an extremely compact, an easy to use solution for adding more functionality and wavelengths either to a system design or lab set-up. It is the simplicity and compactness which makes the multi-line laser very attractive for use in light sheet microscopy.
Through the well-known Swedish laser manufacturer Cobolt AB, a proven supplier of high performance lasers of more than 15 years, HÜBNER Photonics division offers one of the industry’s broadest ranges of compact single-frequency CW lasers, diode lasers, multi-line lasers and Q-switched lasers across the full UV-Visible-NIR spectrum.
