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.

There is a number of different kinds of lasers available at 785 nm. They offer different performance and cost characteristics, which means a careful selection can be important to find the best solution for a particular Raman spectroscopy set-up. In this post we summarise the available technologies around 785 nm.

Until recently, ultrasound and X-ray imaging systems were the only technologies that could look inside a product and detect impurities that are not visible from the outside. Until the T-SENSE was available. It is a terahertz-based system that is both non-contact and radiation-free. Read more!

Most early attention has focused on nitrogen vacancy centres in diamond − which offer single-photon emission at room temperature − but they are not ideal for all applications because their asymmetric charge distribution makes them sensitive to local fluctuations in the electric field. Read how our C-WAVE tunable laser helps researchers find new colour centers candidates.

Read how the Cobolt Skyra multi-line laser is allowing more compact flow cytometry systems with increased functionality. Our editorial from Laser Focus World in June 2019 explains the options.

Raman spectroscopy provides an intrinsic label-free contrast mechanism from the sample that is rich in biochemical content. Taking 2D information of the molecular distribution that conforms the sample is thus, very attractive to the biomedical science community. Read about how the unique combination of Raman and light sheet microscopy is helping us learn more.

As quantum sensing technology has matured over recent years, one of the contending techniques for commercially developed systems is based on nanoscale magnetometry with Nitrogen-Vacancy (NV) centers in diamond. Read our editorial here.

State-of-the-art OPO technology delivers visible, single frequency, tunable laser light from 450 nm – 650 nm. Read about our unique solution to achieve single frequency cw tunable light in the visible to MIR regions.

Lasers are primarily used for high-resolution and high-throughput imaging techniques, and each wavelength excites a different set of fluorophores. In order to efficiently excite multiple fluorophores, it is necessary to use many single-wavelength lasers in one instrument or experiment. Read how our multi-line laser helps make life simpler in instrument design as well as the lab.

A simplified solution for integrating multiple laser wavelengths into a fluorescence microscope is to use a multi-line laser solution. It is now possible to deliver up to four laser colors from one compact and permanently aligned laser package. Read about how it works here.
