“Fiber-coupled acousto-optic modulators” (FCAOM) is perhaps not a phrase that rolls naturally off the tongue. Yet this slightly awkward descriptor belies an elegant and robust solution for directly controlling the timing, intensity, and temporal shape of the output from fiber lasers – which enables them to be used in some of the most demanding applications in the world, including quantum and space.

The launch of G&H’s new EAR certified NightCrawlIR^TM infrared zoom lenses, under the StingRay brand, marks a step change in accuracy, repeatability, and cost-effectiveness in the mid-wave infrared (MWIR) imaging space, in critical sectors including aerospace and defense (A&D), and border security.

When a manufacturing facility producing high-reliability components for long-distance submarine cables suddenly has to triple its output of couplers for prestige clients, meeting this demand is literally a tall order. But this is exactly what happened at our Torquay facility.

Lidar (light detection and ranging) is pushing the boundaries of how we analyze, interpret, and understand both earth and space environments from afar – and G&H’s lidar solutions already underpin many international remote sensing projects and programs. 

Photonics Emerges Stronger from the Pandemic, Proving its Robustness and Resilience Against Market Disruptions. In this article G&H explores the demand for photonics-based solutions across sectors, applications and pain-points, and set out industry needs for photonic components to address the challenges customers face today.

Space is perhaps no longer ‘the final frontier’, but as an operating environment for optical components it remains in many ways the ultimate test of the technology’s reliability, resilience, and precision – far more so, typically, than with terrestrial applications.

G&H's A&D Business Development Manager, Trevor Cook discusses approaches to high-performance SWIR lens designs, by explaining technical challenges in more detail, addressing effective solutions.

OCT systems manufacturers need to deliver systems capable of higher resolution imaging, faster and at lower costs than ever before, posing a challenge. To achieve fit for purpose components and systems that are to specification, budget and timeline at scale, whilst reducing costs over the product lifetime, the challenge requires efficient and effective system design.

Using photonics technologies to establish communications in air-to-ground, air-to-air, and air-to-space fields offers many advantages related to transmission speed, low SWaP systems, spectrum regulations, and immunity to electromagnetic interference.

To analyze the specific damage characteristics of high-power laser optics, it is important to understand the laser induced damage threshold (LIDT), an analytical threshold determination method that can reveal damage diagnostics, and its testing provides a lower-cost option for coating development. 

When designing micromaterial processing equipment, manufacturers need to consider a complex interplay of factors, such as accurate positioning of lasers for cutting, drilling, scribing, or  marking at the highest rate possible. In many integrated circuits, the required beam accuracies can be staggering. 

Optical coherence tomography (OCT) can be used in many medical applications including displaying real-time details of eye diseases, detecting skin cancer, or monitoring heart surgery. The OCT market is set to grow even further over the next few years as the efficiency and effectiveness of imaging improves.

The broad emission spectrum of thulium fibers, which can extend from 1600 to 2200 nm, makes a thulium fiber laser an excellent choice for building widely tunable fiber lasers. This paper details G&H results testing an all-fiber thulium laser system that can be tuned to any wavelength between 1710 to 2110 nm, without using any moving mechanical parts.

The ISLA project was a research and development project with the goal of developing “building block” components of compatible and self-consistent active and passive fibers, fused fiber couplers and combiners, fiber-coupled isolators, modulators and high power pump laser diodes.
