High-Power Broadband Multispectral Source on a Hybrid Silicon Chip

Photonic integrated circuits (PIC) may expand the spectral bandwidth of currently available optical sources at lower cost, smaller size, reduced vibration sensitivity, and higher brightness.

For applications in manufacturing, remote sensing, medicine, military, and fundamental science, an ideal laser would have high output power and a diffraction-limited beam. The figure-of-merit to describe this property is the brightness, which scales proportional to output power and inverse to the beam quality factor M2.

Eliminating Electrical Arcing in Satellite Systems

In 1995, Boeing Satellite Systems introduced a new family of communication satellite buses, with bodies that contain power, control, and propulsion systems. They used a high-voltage bus connected to a 100V stabilized power source, instead of the standard 27V. This introduced an increase in operating voltage that decreased operating currents and lowered the corresponding ohmic losses in the conductors. However, it also introduced a potentially catastrophic failure to the satellites’ electronic systems: electrical arcing (Figure 1).

Stimulated Brillouin Scattering (SBS) Suppression and Long Delivery Fibers at the Multikilowatt Level with Chirped Seed Lasers

Using chirped seed amplification with a MEMS VCSEL seed to scale the output power of a ytterbium fiber amplifier.

One obstacle in the scaling of high-power fiber lasers arises because of nonlinear effects (e.g., stimulated Brillouin scattering [SBS]) due to the large intensity times length product. Efforts to raise the power threshold include:

Erbium Doped GaN Lasers by Optical Pumping

Studying ER:GaN materials under 980 nm resonant excitation could guide future crystal growth.

The main objective of this research was to construct an optical pump system that would allow the study of Er:GaN materials under 980 nm resonant excitation to be carried out. The results obtained from the optically pumped studies could then be utilized to guide crystal growth and laser design.

Saft was recently selected by Aero Vodochody Aerospace, a leading designer and manufacturer of military and civilian aircraft, for engine starting and emergency backup batteries for the L-39NG jet trainer program. Saft has worked in partnership with Aero Vodochody to develop a new 44 Ah version of its ULM (Ultra Low Maintenance) battery with aerobatic capabilities. It’s not the first time Saft has worked with Aero Vodochody; Saft already supplies batteries for the L-159 and the existing L-39 platforms.

New Class of Excimer-Pumped Atomic Lasers (XPALS)

Research demonstrates the viability of an atomic laser having a quantum efficiency greater than one.

The focus of this research program was the investigation of XPAL properties, and new pumping schemes, as well as modeling, and measuring critical photoionization and excited state-excited state reaction rates in order to improve the performance of XPALs.
