Laser-pumped white light source LS-WL1
Powerful point light for multimode fibers

The LS-WL1 laser-pumped white light source generates an extremely bright point light through two blue laser diodes with an output of up to 16 W focused on a ceramic phosphor converter.
The lasers are integrated on one chip with the converter (system on chip). This results in a construction design that is very compact and stable.
The highly efficient optics of the LS-WL1 allows the luminescence emitted by the converter to be coupled into multimode fibers with a diameter of 50 µm to 1 mm. The user receives a flexible point light source with extreme luminance. In terms of light throughput and luminance, the optimum fiber diameter is approximately 600 µm.
The LS-WL1 can achieve switching frequencies of up to 200 kHz via the trigger input. The pulse width and delay are programmable – ideal for synchronization with cameras or sensors. Through its integrated frequency generator, the laser-pumped white light source becomes a high-frequency stroboscope.

The signal output of the LS-WL1 can be used as an input for additional LS-WL1 devices, which, for example, allows light to be staggered from different directions.

The LS-WL1 at a glance:

The LS series (LS-WL1, LS-MC1, LS-BB1) of compact light sources is operated via a USB/RS-232 interface and programmed via simple ASCII commands. This allows easy integration into any programming environment of choice. The delivery scope includes a comfortable GUI for controlling of several LS-WL1 devices.

Our HighLight: Laser-pumped converter phosphor

The extremely high luminance of the LS-WL1 comes about through two powerful laser diodes that pump a stable ceramic phosphor converter with high co-efficiency.
Due to its system-on-chip technology (SoC) for laser and converter, the LS-WL1 has been kept very compact and can be easily integrated as a laser-pumped white light source into existing overall systems.
