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)...

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,...

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...

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 second application note titled "Laser Source Requirements for Modern Laser...

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...
