A scalable source of single photons is a key constituent of an efficient quantum photonic architecture. To realize this, it is beneficial to have an ensemble of quantum emitters that can be collectively excited with high efficiency. Semiconductor qua

Randomized clinical trial of prophylactic transanal irrigation versus supportive therapy to prevent symptoms of low anterior resection syndrome after rectal resection

Autor: H. R. Rosen, W. Kneist, A. Fürst, G. Krämer, J. Hebenstreit, J. F. Schiemer

Publikováno v: BJS Open, Vol 3, Iss 4, Pp 461-465 (2019)

Background Low anterior resection syndrome (LARS) is a frequent problem after rectal resection. Transanal irrigation (TAI) has been suggested as an effective treatment in patients who have developed LARS. This prospective RCT was undertaken to evalua

100 W, Tunable In-band Pumped Thulium Fiber Amplifier

Autor: Stefan Nolte, Nathan Bodnar, Joshua Bryan, Patrick Roumayah, Thorsten A. Goebel, Ria G. Krämer, Nicholas Vail, Alex Sincore, Justin Cook, Martin Richardson

We detail the design and performance of a high efficiency in-band pumped thulium fiber amplifier operating at the 100 W level. Using a novel pumping architecture based on three incoherently combined thulium fiber oscillators at 1904 nm and a seed las

First steps in the development of next-generation chirped volume Bragg gratings by means of fs laser inscription in fused silica

Autor: Evgeny A. Perevezentsev, Malte Per Siems, Daniel Richter, Ivan B. Mukhin, Ria G. Krämer, Anton I. Gorokhov, Mikhail R. Volkov, Stefan Nolte

The first steps towards the development and characterization of next-generation chirped volume Bragg gratings (CVBGs) by means of fs laser inscription were made. Based on the phase mask inscription technique we realized CVBGs in fused silica with a 3
