“…This faster rate is most likely caused by an excited state electron energy transfer, as discussed for similar Pyrromethene dyes in Ref. [46]. The electron energy transfer is from the excited state of the acceptor dye to the ground state of the donor dye.…”

A broadband dye laser pumped by a frequency-doubled Nd:YAG laser with a full-width half-maximum (FWHM) from 592 to 610 nm was created for the use in a dual-pump broadband CARS system called WIDECARS. The desired broadband dye laser was generated with a mixture of Pyrromethene dyes as an oscillator gain medium and a spectral selective optic in the oscillator cavity. A mixture of Rhodamine dyes were used in the amplifier dye cell. To create this laser a study was performed to characterize the spectral behavior of broadband dye lasers created with Rhodamine dyes 590, 610, and 640, Pyrromethene dyes 597 and 650 as well as mixture of these dyes.

“…4,6,14 We have recently reported the enhanced photodegradation of Pyrromethene 567 and Pyrromethene 597 by Pyrromethene 546 via electron transfer. 28 The photoexcited Pyrromethene 567/597 donates an electron to Pyrromethene 546 initiating photodegradation. In that pyrromethene system a competition exists between dye electron donation and 1 O 2 photooxidation.…”

“…The adhesive was cured after each dispensing step in a nitrogen environment using an LED-based UV curing system (365nm LED head, Aicure UJ35, Panasonic). Curing under nitrogen minimizes any UV-induced degradation of the organic dye by minimizing the concentration of oxygen [34]. The output power of the curing lamp was set to approximately 1.2 W/cm 2 on the surface of the sensor chips, with 15 seconds of curing time for each dispensing step.…”

Whispering-gallery mode (WGM) microdisk lasers show great potential for highly sensitive label-free detection in large-scale sensor arrays. However, when used in practical applications under normal ambient conditions, these devices suffer from temperature fluctuations and photobleaching. Here we demonstrate that these challenges can be overcome by a novel referencing scheme that allows for simultaneous compensation of temperature drift and photobleaching. The technique relies on reference structures protected by locally dispensed passivation materials, and can be scaled to extended arrays of hundreds of devices. We prove the viability of the concept in a series of experiments, demonstrating robust and sensitive label-free detection over a wide range of constant or continuously varying temperatures. To the best of our knowledge, these measurements represent the first demonstration of biosensing in active WGM devices with simultaneous compensation of both photobleaching and temperature drift.
