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...

Laser diodes have been approved for use by the FDA for dental use for over 20 years, and have now become the most commonly used laser in dentistry.  The most commonly used laser procedures in the dentistry are crown troughing, pocket disinfection,...

The popularity of laser induced breakdown spectroscopy (LIBS) has been rapidly growing since its introduction in the 1960s, and is now used in industrial, military, scientific, and medical applications.  Nowadays LIBS is rapidly becoming an...

Optical technologies have been widely deployed in anti-counterfeiting for many years including holograms, fluorescent tags, and dichroic inks.  One of the newer techniques used to fight the never-ending war on counterfeiting uses a combination of...

If you have been following our blog these past few months then you may already be familiar with many of the recent changes that we here at RPMC have been making to our website in order to provide the community with the most up to date knowledge of...

Here at RPMC Lasers, we thought it would be fun to give all of you a chance to test your laser knowledge with a new series of 10 question quizzes.  The first quiz in our new series covers a wide range of laser topics including laser fundamentals,...

On October 2nd the Royal Swedish Academy of Sciences announced this year’s Noble prize in physics was being awarded “for groundbreaking inventions in the field of laser physics.”  This year’s award is to be split between two different inventions...

Laser line generators are widely used in machine vision for a broad variety of inspection applications.   When used for the inspection of small parts laser lines and other shapes are typically achieved through the use of diffractive optical elements...

During any manufacturing process, there is some statistical variation in the finished product.  Resistor manufacturing is no different, and for many years traditional bulk and chip resistors have been tested and sorted into bins and labeled based upon...

One of the most challenging tasks in any aerial combat situation is to determine which assets on the ground should be targeted and which ones should be avoided.  This is particularly challenging in the situation where enemy assets are camouflaged or...

In our last blog post, “Laser Amplification for Power Scaling,” we discussed how an optical amplifier can be used to increase the power of a seed laser while maintaining its performance characteristics.  The same basic principle can be applied to a...

Modern lasers come in a seemingly endless variety ranging from diode lasers as small as a grain of rice to CO2 lasers the size of a refrigerator.  The one thing that all of these lasers have in common is that they contain the three basic components of...

Here at RPMC Lasers, we understand the importance of continuing education and professional development.  Over the past few months, we have been making an effort to do our part to help you enhance your laser knowledge base, starting with the...

Continuing with our recent theme of application for laser diode bars and stacks, in this post we will take a look at laser cladding.  If you haven't already read our previous post titled "Understanding Laser Diode Arrays," or have a basic...

In a one of last weeks post titled "Understanding Laser Diode Arrays," we examined how laser diode bars and stacks can be used to generate extremely high-powered direct diode laser sources.  In this post, we will look at how these lasers can be used...

Two weeks ago we published a blog post looking at time-of-flight (TOF) laser radar, now in this post, we are going to a look at what happens when you combine this technique with near-infrared (NIR) imaging in order to do active night vision imaging. ...

At RPMC we offer one of the widest ranges of laser diodes on the market, and if you have been following us for some time now we often mention that we offer both single emitters and arrays (bars).  In this blog post we are going to take a look at...

Once thought to be impossible, blue, green and UV laser diodes have now become commonplace.  These lasers are being used in a wide range of applications from blue-ray players to commercial lighting & displays to copper welding.  In this post, we are...

Raman spectroscopy is one of the fastest growing and most diverse applications in all of laser spectroscopy.  As a result, it can be rather challenging at times to sift through the wide-ranging laser options all being marketed for Raman spectroscopy. ...
