Pulsed Lasers White Papers

After reading this white paper, you will come away with an in-depth understanding of both the history of night vision technology, as well as the current state of modern night vision imaging. This article will further go on to explain the important features and requirements that you need to be aware of when determining which laser source is best for your active imaging application. In this article, we illustrate the critical laser requirements through Optitask’s series of q-switched Er:Glass lasers, which are ideally suited for active night vision imaging, due to both their ruggedized design and high pul… Read More

Understanding brain function requires monitoring local and global brain dynamics. Two-photon imaging of the brain across mesoscopic scales has presented trade-offs between imaging area and acquisition speed. We describe a flexible cellular resolution two-photon microscope capable of simultaneous video rate acquisition of four independently targetable brain regions spanning an approximate five-millimeter field of view. With this system, we demonstrate the ability to measure calcium activity across mouse sensorimotor cortex at behaviorally relevant t… Read More

Are you looking for a high-power, high repetition rate, femtosecond fiber laser for your bioimaging application? This white paper, provided by Jerry Chen of Chen Labs at Boston University, details their successful experiment, identifying spectral variants of the recently developed jGCaMP7 family of GECIs, resulting in the development of jYCaMP, a red-shifted variant, perfectly suited for fiber laser wavelengths. Within the experiment, Chen Labs utilized a 31.25MHz, 1040nm, Altair fiber laser from SPA… Read More

After reading this white paper, you will come to understand the fundamental rationale behind range resolution not being of particular importance for this application and why continuous wave (CW), frequency modulated LiDAR signals are preferred over pulsed laser signals. This article will further go on to provide a brief overview of fiber laser technology and explain why they have become the light source of choice for most commercial LiDAR applications.  Lastly, in the article, the LRL2 single-frequency fiber laser from BKtel is presented as an example of a perfect laser solution with the specifications required to lay the foundation for a successful Doppler LiD… Read More

After reading this white paper, you will come to understand the fundamentally entangled relationship between the range and velocity resolution of a lidar system and why it is so important to use single frequency laser sources for velocity measurement. This article will further go on to provide a brief overview of fiber laser technology and explain why they have become the light source of choice for most commercial lidar applications. Lastly, in the article, the LRL2 single frequency fiber laser from BKtel is presented as an example of the types of specifications required to lay the foundation for a successful Doppler lid… Read More

Ultra-fast mode-locked lasers have enabled two-photon microscopy, also referred to as multiphoton microscopy, to revolutionize the biological imaging.  This technique now allows users to create high-resolution fluorescence images of living cells, without damaging the cells in the process. In this article, we will explore how two-photon microscopy has evolved over the years and the integral role that the mode-locked laser has played in its evolution.  It will also discuss the impact of laser wavelength on two-photon absorption and the advantages of working at 920 nm.  Lastly, this article will introduce the development of the Alcor laser series by Spark Lasers, which is the ideal excitation source for two-photon microscopy when working at 920 nm an… Read More

We have published an extensive amount of educational content on the fundamentals of LiDAR as well as various LiDAR applications, including self-driving cars, windspeed monitoring, and active night vision imaging systems. In this white paper, we take a much different approach and discuss the wide variety of laser options that RPMC offers for various LiDAR applications. The white paper is broken into three distinct sections, each one highlighting a different type of laser (fiber lasers, DPSS lasers, and microchip lasers). In each section, we will not only discuss the various product offerings but also pair them with the most relevant LiDAR applications for thos… Read More
