Space Qualified 2-Pin Package
Sheaumann teamed with Tesat-Spacecom in 2015 to develop a space-qualified laser module which is now used in LEO and GEO satellites. This intensive three-year project required an enhancement of Sheaumann’s flagship 2-Pin “SheauPac” module to perform...
Spectral Density Contrast in DPSS and ECD Lasers for Quantum and Other Narrow-linewidth Applications
With current endeavours in the UK and around the world to foster the development of new Quantum-based technologies (QT) to sense and detect previously unreachable interactions, such as underground structures and gas leakages, the generation of light...
High-Power TO-Can
A high-power, continuous-wave, TO-Can package with single-mode power up to 600 mW and multimode power up to 3 W.
Light Changes Matter – with Optics, Lasers and Sensors
Jenoptik is a global OEM supplier of solutions and products based on photonics technologies with more than 25 years experience in the fields of optics, laser technology, digital imaging, opto-electronics and sensors. Our customers work in areas such...
PDH Technique with Moku:Lab’s Laser Lock Box — An FPGA-based all-in-one Solution for Laser Frequency Locking
The Pound-Drever-Hall (PDH) technique was first introduced by R.V. Pound, Ronald Drever, and John L. Hall in 1983. It is a widely used method to match the emitting optical frequency of a laser to a Fabry-Perot cavity. PDH locking uses light...
Laser Sources for LiDAR Applications
RPMC has published an extensive amount of educational content on the fundamentals of LiDAR and LiDAR applications, including self-driving cars, windspeed monitoring, and active night vision imaging systems. Here, we'll take a different approach and...
High-Volume, Cost-Effective Uniform Deposition for Flat and Curved Optical Surfaces
To achieve thin film uniformity on flat surfaces, nearly every conventional physical vapor deposition (PVD) method requires masking, complex motion, or both. For curved surfaces, none of these methods are capable of delivering similar uniformities,...
Isolated C-Mount
Our isolated C-Mount is built to integrate seamlessly as a direct replacement of our standard C-Mount.
Next Generation Two-photon Microscopy using the FemtoFiber Ultra 920 Fiber Laser
Two-photon fluorescence microscopy has become a key technology in biological imaging enabling three-dimensional, noninvasive studies of biological tissue on the submicron scale. To boost the usability of this method and to provide an ultracompact,...
Focused on Possibility. What would you like to Achieve?
What do you want to achieve? Sheaumann is dedicated to innovation, rigorous quality control, and assisting in the development of new technology. Looking for a US-based, vertically integrated partner with some serious engineering chops?
Camera-based Observation in Laser Material Processing
Camera-based imaging enables real time observation and feedback during laser processing. This paper gives you an overview about several methods of camera-based observation to find the best solution for your application.
Health and Sanitization through UV Lighting
With increased awareness and necessity for rapid disinfection methods due to the current coronavirus pandemic, ultraviolet disinfection has become a viable method to achieve it. Determining the amount of UV energy the light source emits onto the...
Wavelength Stabilized Fiber-coupled Laser Modules for DPSS and Fiber Laser Pumping
nLIGHT continues to drive innovation in multi-emitter diode modules, as demonstrated by successfully reducing our laser diode voltage by means of a revised epitaxy across multiple wavelengths, and then demonstrating module level results of these new...
3SAE End-Cap Fusion Splicer (ECS)
The world's first portable end-cap fusion splicer that provides capabilities that overcome the limitations of current end-cap splicing processes.
Tunable Light Speeds up the Search for the Perfect Qubit
One of the most promising candidates for the perfect quantum qubit are defect centres in solid-state materials, also known as colour centres, which have been found to emit a single photon per excitation event when excited by laser light of a...
Robust 785 nm lasers for Raman by Cobolt
HÜBNER Photonics is one of the leading suppliers of all laser wavelengths to the high resolution Raman spectroscopy market and now introduces the 08-NLDM 785 nm ESP (enhanced spectral purity) as part of the Cobolt 08-01 Series. The 08-NLDM 785...
Light-Emitting Diodes: A Primer
This article will provide an overview of the LED operation and a brief look at the industry. Various types of LEDs, the corresponding wavelengths, materials used in their composition, and some applications for the specific lamps will also be...
New Approach for High Reliability, Low Loss Splicing between Silica and ZBLAN Fibers
This paper presents results obtained by using the high thermal expansion coefficient of the ZBLAN fiber to encapsulate a smaller SiO2 fiber. A CO2 laser glass processing system was used to control the expansion and contraction of the ZBLAN material...
Photodigm HOT™ DBR Lasers
The Photodigm family of high-power edge-emitting Distributed Bragg Reflector (DBR) laser diodes is based on Photodigm’s proprietary single epi growth DBR laser architecture. Since their introduction over 10 years ago, Photodigm DBR lasers have...
Industrial Laser Measurement Systems: Best Practices
When discussing laser applications, regardless of how the laser is used, it is imperative to understand how the laser is interacting with the material being processed. This article will detail why a laser’s performance is important for industrial...
Annular Heating of Optical Fiber with a CO2 Laser Using Reflective Axicon Elements
By offsetting the light structure, precise localized zone heating and annealing of specific areas at a fiber’s surface can be achieved as well. This is essentially a passive device into which active feedback elements can be incorporated to allow...
