HOT PRODUCTS

G&H's Pockels Cells enable higher performance and reliability across numerous laser applications, providing increased optical power. The standard product ranges can accommodate wavelengths from from UV to IR (200 nm -12 μm).

Applied in many fields, including avionic and space communications, biomedical instrumentation, fiber laser systems, industrial micromachining, interferometry, lidar, medical diagnostics, optical coherence tomography (OCT), sensing, and telecommunications, G&H's fused fiber components play a vital role in aligning and marrying individual cable fibers.

G&H Fused Fiber Optic Components feature a range that has been expanded to include the 2 µm operating window. With multiple housing and pigtail options, these products are able to be used for many different applications. 

G&H offers a variety of Housings, Connectors, And Patchcords, differentiated by housing type and pigtail. G&H can provide its components and modules terminated with a wide variety of connectors.

Applied in many fields, including avionic and space communications, biomedical instrumentation, fiber laser systems, industrial micromachining, interferometry, LIDAR, medical diagnostics, optical coherence tomography (OCT), sensing, and telecommunications, G&H's Fiber Lasers can be used to perform cutting, marking, welding, cleaning, texturing, drilling and more. 

Polarization-maintaining (PM) fiber provides additional functionality in fiber optic systems, where the birefringence feature of the fiber allows propagation of two polarization states. Utilization of this is applied across diverse fields including, sensing, telecommunications, fiber laser system, interferometry, medical diagnostics and industrial machining.

Applied in many fields, including avionic and space communications, biomedical instrumentation, fiber laser systems, industrial micromachining, interferometry, LIDAR, medical diagnostics, optical coherence tomography (OCT), sensing, and telecommunications, G&H's Single-Mode Couplers play a vital role in aligning and marrying individual cable fibers.

G&H offers a range of distributed feedback lasers (DFB) that provide smooth, tunable wavelength control and the narrow spectral width required for precise fiber optics. Applications for these products include spectroscopy and fiber optic communications.

G&H designs and manufactures custom modules including fiber assemblies of passive and/or active optical components. Customers sourcing fiber optic assemblies are looking to reduce time to market and development costs. 

The G&H NightCrawlIR series utilizes unique aperture-specific foreoptics and a modular base to maximize performance, while staying budget-friendly. These lenses are purpose-built from the ground up for the demands of high resolution applications.
