Method For Laser Source Definition in ZEMAX™

In a recent article, Alexander Brodsky and Natan Kaplan of Holo/Or present “a new method for simulating and optimizing both single and multi-mode lasers in Zemax™ by applying a scattering model.” The abstract of the article follows: By default, optical systems are usually designed for single mode lasers. Nonetheless, many industrial lasers have M2 in … Continue reading

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
