Ring-doped cladding-pumped single-mode three-level fiber laser.

Optics letters

Nilsson J, Minelly JD, Paschotta R, Tropper AC, Hanna DC.
PMID: 18084510
Opt Lett. 1998 Mar 01;23(5):355-7. doi: 10.1364/ol.23.000355.

We propose and theoretically analyze three-level cladding-pumped fiber lasers in which the laser-active dopant is placed in a ring around a single-mode core. A ring-doped laser can work efficiently at wavelengths with strong small-signal absorption. This is otherwise difficult...

240-fs pulses with 22-W average power from a mode-locked thin-disk Yb:KY(WO(4))(2) laser.

Optics letters

PMID: 18026394
Opt Lett. 2002 Jul 01;27(13):1162-4. doi: 10.1364/ol.27.001162.

We demonstrate what is to our knowledge the first passively mode-locked thin-disk Yb:KY(WO(4))(2) laser. The laser produces pulses of 240-fs duration with an average power of 22 W at a center wavelength of 1028 nm. At a pulse repetition...

Quantum-limited noise performance of a femtosecond all-fiber ytterbium laser.

Optics express

Opt Express. 2009 Aug 31;17(18):15525-33. doi: 10.1364/OE.17.015525.

We report on quantum-limited noise performance of a mode-locked ytterbium all-fiber laser. The laser operates at a high normal net dispersion without dispersion compensation. We show that the naïve application of analytical models to such lasers leads to strongly...

PMID: 33512368
Recenti Prog Med. 2021 Jan;112(1):14e-15e. doi: 10.1701/3525.35133.

BACKGROUND: Translocation-associated renal cell carcinoma involving ALK (ALK-tRCC) is a rare subtype of adult renal cell carcinoma (RCC) reported in recent years.CASE PRESENTATION: A new Italian case of ALK-tRCC was reported. The patient was a female 44-year-old with a...

Temperament and character effects on late adolescents' well-being and emotional-behavioural difficulties.

Crescentini C, Garzitto M, Paschetto A, Brambilla P, Fabbro F.
PMID: 29607254
PeerJ. 2018 Mar 27;6:e4484. doi: 10.7717/peerj.4484. eCollection 2018.

BACKGROUND: Research on adults points to personality as a crucial determinant of well-being. The present study investigates the question of personality's relation to well-being and psychosocial adjustment in adolescence.METHODS: We assessed the role of temperament and character (Temperament and...

Nearly quantum-noise-limited timing jitter from miniature Er:Yb:glass lasers.

Optics letters

Schlatter A, Rudin B, Zeller SC, Paschotta R, Spühler GJ, Krainer L, Haverkamp N, Telle HR, Keller U.
PMID: 16007799
Opt Lett. 2005 Jun 15;30(12):1536-8. doi: 10.1364/ol.30.001536.

We report on nearly quantum-limited timing-jitter performance of two passively mode-locked Er:Yb:glass lasers with a repetition rate of 10 GHz. The relative timing jitter of both lasers was measured to be 190 fs (100 Hz-1.56 MHz) root mean square....

Practical low-noise stretched-pulse Yb(3+)-doped fiber laser.

Optics letters

Lefort L, Price JH, Richardson DJ, Spüler GJ, Paschotta R, Keller U, Fry AR, Weston J.
PMID: 18007780
Opt Lett. 2002 Mar 01;27(5):291-3. doi: 10.1364/ol.27.000291.

We report on the development of what we consider to be a practical and highly stable stretched-pulse laser based on Yb(3+) -doped silica fiber. The Fabry-Perot cavity uses nonlinear polarization rotation as the mode-locking mechanism, and a semiconductor saturable-absorber...

Widely tunable pulse durations from a passively mode-locked thin-disk Yb:YAG laser.

We demonstrate a passively mode-locked thin-disk Yb:YAG laser that generates solitonlike pulses with durations that are continuously tunable in a very wide range from 3.3 to 89 ps or from 0.83 to 1.57 ps. The average powers are typically...

We report on a simple diode-pumped passively mode-locked Er:Yb:glass laser generating transform-limited 1536-nm solitons of 255-fs duration with a repetition rate of 50 MHz and average power of 58 mW. We also discuss timing jitter and the trade-off between...

We present a singly resonant, synchronously pumped optical parametric oscillator with a record-high repetition rate of 39 GHz. The transform-limited 2.2-ps pulses at 1570 nm have as much as 2.1-W average output power. The all-solid-state pump source is based...
