Holography is simultaneously one of the most well-known and yet most misunderstood optical techniques.  The word hologram derives from the combination of two different Greek words “holo” meaning “whole” and “gram” meaning “drawing.”  Understanding the...

Optical particle counting is widely deployed in cleanrooms around the world as a means for counting and sizing the number of particles in the air.  Most people who have ever worked in a clean room, are familiar with the Federal Standard 209E cleanroom...

According to the American Association of Dermatology (AAD), acne is the most common skin condition in the United States, affecting up to 50 million Americans annually with a nontrivial percentage suffering from a chronic form of the condition. ...

There are two critical parameters that all lasers diodes must meet to begin the lasing process.  The first one of these parameters is that there must be more gain than loss inside the laser cavity, the point at which this condition is satisfied is...

At RPMC we are excited to announce the release of our newest lidar white paper titled "Single Frequency Fiber Lasers for Doppler Lidar."  Doppler lidar takes advantage of the fact that when light interacts with moving object, it experiences a...

Last summer we released a white paper titled "How Mode-Locked Lasers Affect the Past, Present, and Future of Two-Photon Microscopy" which reviewed in detail the evolution of two-photon microscopy, with a particular focus on its usefulness in producing...

Mass spectrometry is an extremely powerful analytical tool for chemical analysis, which is widely utilized in applications ranging from forensics to pharmaceuticals, because of its ability to detect the atomic constituents of an analyte but also...

Building upon the success of our widely popular whitepaper titled “How to Improve Laser Diode Lifetime! Advice and Precautions on Mounting,” we at RPMC Lasers, have decided to expand on this topic offering a brand-new application note titled...

Laser hair removal is one of the most popular medical laser applications worldwide and is projected to reach 1.35 billion dollars annually by the year 2022 according to Transparency Market Research. As this market started to explode in the early...

As discussed in previous posts, Raman spectroscopy is a rapidly growing analytical technique used in a wide variety of industries for material identification, but with so many different laser options it can be somewhat challenging to understand which...

Whether a diode laser is a traditional monolithic design or utilizes an external cavity configuration, the laser light must still propagate through the diode’s PN-junction via a ridge waveguide.   As a result, the beam profile of edge emitting diodes...

Last week RPMC Lasers, was proud to show our support for the photonics community once again by exhibiting this year at SPIE’s Photonics West conferences in San Francisco.  It was a great event this year, especially with the completion of the recent...

Photodynamic therapy (PDT) is a common term in the medical community which has been used to describe treatments ranging from near-infrared laser-induced vascular dilatation to photo-thermal excitation of nanorods embedded in cancer tumors.    For the...

In our previous application note titled “Laser Induced Breakdown Spectroscopy (LIBS) in Biomedical Applications,” we discussed the fundamentals of the technique with a particular emphasis on the use of q-switched diode-pumped solid-state lasers as the...

Laser-based techniques have been gaining more and more popularity in the medical and biomedical fields.  In previous posts, we have discussed a wide variety of such applications ranging from Laser Diode Crown Troughing in Dentistry to Laser-Induced...

As part of our commitment to helping to promote the latest advancements in the laser and electro-optic community, we here at RPMC Lasers would like to take a moment to shine a spotlight on one of the conferences in our community that does just that...

Here at RPMC Lasers we are excited to announce our exclusive North American distribution relationship with The Bright Solutions Group,  providers of state-of-the-art pulsed DPSS lasers.  For over 15 years we have worked closely with Bright Solutions,...

At RPMC we are excited to announce the release of our most recent white paper focused on fluorescence microscopy titled "Multi-Wavelength Laser Sources for Multi-Color Fluorescence Microscopy."  Multi-color fluorescence microscopy is a widely used...

RPMC Lasers is excited to be participating in The American Society for Cell Biology (ASCB) 2018 meeting in San Diego from December 8th to the 12th.    ASCB is an inclusive, international community of biologists studying the cell, the fundamental unit...

As promised we here at RPMC Lasers, would like to give you another chance to test your laser knowledge with a new 10 question quiz.  The first quiz in our this series covered a wide range of laser topics including fundamentals, historical trivia, and...

Semiconductor materials are unique among laser gain materials for their extremely high index of refraction.  As a result of this large index difference at the air/semiconductor interface, each facet of a laser diode naturally acts as a partially...

Raman spectroscopy allows for the investigation of vibrational modes of a molecule, by measuring the frequency shift of scattered laser light.  This works because the difference in energy between the incident wavelength and the scattered wavelength is...

Technically speaking fiber lasers are a specific subset of diode pumped solid-state lasers (DPSS), even though their unique qualities tend to get them placed in their own category.  As a diode pumped laser, fiber lasers take advantage of the shape of...

RPMC Lasers is excited to be participating in Neuroscience 2018 in San Diego from November 3-7.     As the leading event in the field of neuroscience, Neuroscience 2018 provides us with an opportunity to share our laser technology and knowledge with...

As part of our continued effort to continually provide you with the most up to date information on laser technology and application, we are proud to announce the release of our third application note titled "Laser Induced Breakdown Spectroscopy (LIBS)...
