Observation of Ultraslow Group Velocity of Light in a Solid
Autor: Turukhin, A. V., Sudarshanam, V. S., Shahriar, M. S., Musser, J. A., Hemmer, P. R.
We report ultraslow group velocities of light in a solid. Light speeds as slow as 45 m/s were observed, corresponding to a group delay of 66 ms in a 3-mm thick crystal. Reduction of the group velocity is accomplished by using a sharp spectral feature

High Power EDFAs for Free Space Communication
Autor: J.W. Nicholson, A. Grimes, A. Hariharan, V. Sudarshanam, C. Jin, I. Sun
Publikováno v: Optical Fiber Communication Conference (OFC) 2023.
Progress and performance of high-power EDFAs, in-band pumped by Raman fiber lasers operating at 1480 nm will be reviewed. Applications of these laser systems to free-space communications will be discussed.

High Pulse Energy, Erbium-doped, Very-Large Mode Area Fiber Amplifier
Autor: Venkatapuram S. Sudarshanam, Jeffrey W. Nicholson, Cang Jin, Andrew Grimes, Anthony DeSantolo
Publikováno v: Conference on Lasers and Electro-Optics.
We report pulse energy ~3.85mJ from 1480nm core-pumped, 6m long Er-doped VLMA fiber amplifier with 50µm core diameter and 50dB/m absorption, and diffraction-limited output, by amplifying broad-linewidth microsecond pulses at 10-kHz repetition rate.

Kilo-Watt high-power Yb fiber laser at 1117 nm
Autor: Clifford Headley, Venkatapuram S. Sudarshanam, Kazi S. Abedin, Jeffrey W. Nicholson, David J. DiGiovanni
Publikováno v: Fiber Lasers XV: Technology and Systems.
We report a 1kW, 14 μm-MFD, Yb fiber laser operating at 1117nm, without any parasitic lasing at shorter wavelengths, and negligible intra-cavity Raman gain at longer wavelengths (>50dB extinction at 1175nm). To the best of our knowledge, this is the
