nLight proposes the development of high efficiency, high average power 1550-nm laser transmitter system that is based on Er-doped fiber amplifier resonantly pumped by high efficiency 1532-nm fiber-coupled diode laser pumps. To meet the efficiency requirement for space communication, nLight proposes… More

Compact, Rugged, Multiple Spectral Band Laser

Award Year / Program / Phase: 2013 / SBIR / Phase I
Agency / Branch: DOD / NAVY
Principal Investigator: Kirk Price, Principal Investigator – (360) 566-4460
Award Amount: $79,997.00
Abstract:
nLIGHT proposes the development of a multiple spectral band laser head that is based on a vertically stacked array of single emitter laser diodes. A key design aspect of this device is that the proposed laser head is largely based on a multi-emitter pump module that is currently under commercial… More

Multi-kW Fiber Lasers Based on Novel Light Guide Combiners

Award Year / Program / Phase: 2013 / SBIR / Phase I
Agency: DOD
Principal Investigator: Kirk Price, Principal Investigator – (360) 566-4460
Award Amount: $149,963.00
Abstract:
ABSTRACT: The efficient coherent beam combination of a master oscillator power amplifier (MOPA) system requires a reduction in non-linearities of the power amplifier sections. Fiber non-linearities, such as stimulated Brillouin scattering (SBS) and stimulated Raman scattering (SRS), provide an… More

Coherent Detection Eye-Safe LIDAR Systems Based on Large Mode Area Fiber Amplifiers

Award Year / Program / Phase: 2013 / SBIR / Phase I
Agency: DOD
Principal Investigator: Kirk Price, Principal Investigator – (360) 566-4460
Award Amount: $149,876.00
Abstract:
ABSTRACT: nLIGHT proposes the development of of an all-fiber, master oscillator power amplifier (MOPA) configuration that will meet the Air Force requirements for a 10 mJ, 300 ns pulsed laser source. With the exception of the output power amplifier fiber, this device will be based on commercial… More

High-Efficiency, High-Temperature Laser Diodes for Naval High-Energy Laser Applications

Award Year / Program / Phase: 2013 / SBIR / Phase II
Agency: DOD
Principal Investigator: Zhigang Chen, Princpal Investigator – (360) 566-4460
Award Amount: $149,426.00
Abstract:
Based on the promising results obtained under Navy Phase I SBIR funding, nLight proposes a Phase II continuation toward the development of fiber-coupled high power and high efficiency diode laser pumps around 975 nm that operate at high ambient temperatures. Under the Phase I SBIR base program,… More
