Watch Laser Quantum’s Two-Photon Microscopy Video

Achieving high resolution and increasing imaging speeds are two critical factors for effective two-photon microscopy. Laser Quantum’s newest animation demonstrates how the helixx laser, with a repetition rate of 250 MHz, is tailored to the decay times of typical fluorophores to reduce photobleaching and toxicity, while increasing imaging speed and cell view times. Its short … Continue reading

Enhancing Two-Photon Microscopy

Two-photon microscopy has many advantages over conventional microscopy including: minimal photo-bleaching effect and sample damage, higher imaging depth of live cells, higher excitation efficiency, and simultaneous excitation of multiple fluorophores with the promotion of autofluorescence. Ultrashort (<10 fs) pulses enhance the two-photon microscopy technique. The peak power for a given average output is much higher … Continue reading

Name a Cost-Efficient Open-Source Laser Engine for Microscopy

Researchers from EBML in Heidelberg and University of Jena recently published a paper entitled: “A cost-efficient open source laser engine for microscopy”. The abstract of this paper states: “Scientific-grade lasers are costly components of modern microscopes. For high-power applications, such as single-molecule localization microscopy, their price can become prohibitive. Here, we present an open-source high-power laser … Continue reading

Development of a Terahertz Cyclotron Resonance Spectrometer

In a video, Dr. Darren Graham explains the development of the terahertz cyclotron resonance spectrometer at the Photon Science Institute, University of Manchester. Cyclotron resonance has been about since the 1960’s and the technique has led to the development of new semiconductor materials, producing light-emitting diodes and transistors. In order to perform the techniques, you … Continue reading

Latest PLIM Research Released

A recent scientific paper published in the Journal of Innovative Optical Health Sciences by The Core Imaging Facility at the University of Ulm investigates the use of fast-repetition-rate, fs-pulsed lasers to advance phosphorescence lifetime imaging microscopy (PLIM). PLIM is traditionally performed with 80 MHz Ti:Sapphire lasers; however, this paper highlights the successful application of  250 … Continue reading

Laser Quantum Introduces Ultra-Low-Noise Laser

The newest ultra-low-noise laser, call axiom 532, from Laser Quantum lends itself to Ti:Sapphire pumping as the pump laser noise is transferred directly to the noise of the Ti:Sapphire laser. When the typical noise value is <0.02% RMS, this factor is greatly reduced, even at powers up to 12 W. The exceptional beam profile produced … Continue reading

Solving a Magnetic Raman Scattering Problem

In recent work appearing in the Physical Review, Dr. Mikhail Prosnikov was investigating Magnetic Raman scattering. To calculate some of these delicate measurements in the experiments, he required stable, weakly-divergent and narrow line lasers. The torus 532 laser from Laser Quantum was the perfect tool to use to acquire accurate data and further his research. The … Continue reading
