How Will THIS Homogenized ‘Stub Laser’ Save You Money & Space?

It is well known that the output beam characteristic of a multimode laser diode is inherently non-uniform, due to both spatial and temporal variations of the mode profile, that result from thermal lensing and filamentation.

Why is Polarization Switching Unsuitable for Interferometry?

A common problem for HeNe laser customers is the issue of polarization switching, which is the sudden change of the polarization of different modes, especially in shorter tubes, which can be particularly detrimental when operating frequency stabilized HeNe laser tubes. This phenomenon is sometimes referred to as ‘mode hopping.’ However, this is not accurate. While somewhat similar to polarization switching, mode hopping involves the laser’s operation on a single resonator mode, which suddenly switches to another mode, causing the optical power to switch over to this… Read More

Laser Diode Fundamentals: What are Longitudinal Modes?

Laser diodes must meet two critical requirements to facilitate the lasing process. The first requires that, at a minimum, the laser cavity’s gain increases to the point that it reaches unity with the level of losses. This unity state is known as the gain threshold. The second requirement is that there must be a longitudinal mode present inside the optical cavity, coinciding with the laser’s gain curve. This article explores precisely what longitudinal modes are and how they affect the laser diode’s pe… Read More

Raman Spectroscopy: Why Are Picosecond Pulses Superior to Femtosecond?

Spectroscopy is a class of analysis methods meant for chemical species identification and concentration measurement, based on emission spectra detection, if irradiated by an adequate light source. Fluorescence-based spectroscopy is one of the oldest spectroscopic techniques. This technique utilizes electron-photon interactions and relies on the absorption of high-energy photons and the subsequent emission of lower-energy, longer-wavelength fluorescence photons, with the energy difference associated with vibrationa… Read More

How Does Concatenation Enhance Raman Spectroscopy?

In this blog, the concept of “Raman Concatenation” is explained as a measurement technique utilized to overcome many of the previously outlined trade-offs. In general, many Raman measurements suffer from fluorescence, which forces the use of longer excitation wavelength (lower photon energy) lasers to prevent the fluorescence signal from overwhelming the Raman signal. However, this results in reduced sensitivity of low-cost silicon CCD detectors at higher wavenumbers, making it difficult (or impossible) to observe the “stretch” portion of the Raman spectra (i.e. 2000 – 4… Read More

Key Laser Requirements for Bathymetric and Topographic LiDAR

Shortly after the invention of the first laser, a relevant application enabled by the availability of coherent light, called time-of-flight, emerged. ToF is the precise measurement of the round-trip time of a laser pulse from the source to the target object and back again, allowing you to determine the distance or the velocity of the target. By collecting the back-reflected (or back-scattered) radiation of a short pulse, initially directed to a remote target, it is possible to determine the exact position of said target, provided that the time interval between the outgoing pulse and the corresponding echo is precisely… Read More
