Eye (Lond) . 2024 Oct; 39(1):154-161. PMID: 39406933
Background/objectives: To characterise morphological changes in neovascular age-related macular degeneration (nAMD) during anti-angiogenic therapy and explore relationships with best-corrected visual acuity (BCVA) and development of macular atrophy (MA). Subjects/methods: Post-hoc...

Chakravarty U, Mukhopadhyay P, Kuruvilla A, Upadhyaya B, Bindra K
Appl Opt . 2017 May; 56(13):3783-3788. PMID: 28463269
A narrow-linewidth broadly tunable Yb-doped Q-switched fiber laser using an acousto-optic modulator and multimode interference filter (MMIF) in the linear bulk cavity resonator and an all-fiber ring cavity resonator has...

Chakravarty U, Kuruvilla A, Singh R, Upadhyaya B, Bindra K, Oak S
Appl Opt . 2016 Feb; 55(2):288-96. PMID: 26835764
We report on the generation of 41.6 W of average output power from a passively Q-switched ytterbium-doped fiber laser using Cr4+:YAG crystal as a saturable absorber (SA). This is the...

Upadhyaya B, Kuruvilla A, Chakravarty U, Shenoy M, Thyagarajan K, Oak S
Appl Opt . 2010 Apr; 49(12):2316-25. PMID: 20411011
We report an experimental study of the effect of fiber length and laser linewidth on self-pulsing dynamics and output stabilization of a single-mode Yb-doped double-clad CW fiber laser. It is...

Upadhyaya B, Chakravarty U, Kuruvilla A, Thyagarajan K, Shenoy M, Oak S
Opt Express . 2009 Jun; 15(18):11576-88. PMID: 19547516
The output pulse characteristics of Q-switched Yb-doped fiber lasers have been investigated experimentally. It has been observed that for any typical modulation frequency, the pump power and the modulator OFF-time...
