WLS Fiber Power Density Spectrum

An Oriel 68830 Constant Current Power Supply) attached to a Xenon bulb mounted in an Oriel lamp housing was used to illuminate a 10cm long Kuraray Y-11 WLS fiber, as shown in Figure 1. The power supply was set to about 12W. The fiber was held in place by the monochromator input slits. A spectrum was taken with and without the fiber in place.

Notable differences were observed between the measurements previously recorded here.

The spectra of two different lamps found in the lab are shown below. No specific details are known about each light source. Lamp 1 was used to light the WLS fiber
