A spectrally tunable light source or even a laser has historically always been an expensive solution with low energy efficiency, especially when you need to get as much light as possible onto a small sample area or to bind the output to an optical fiber.
Thanks to Supercontinuum lasers, this is now possible. For many applications, you don't even need to purchase expensive systems, but can make do with compact versions of white lasers.
A functional tunable laser assembly consists of a white laser and a filter module, which can be a standard monochromator, a tunable filter or an optical modulator-based filter (AOTF).
Advantages of a white laser solution
- Preservation of laser beam properties (small beam diameter, divergence)
- High efficiency of output coupling to the fiber
- Single shot up to MHz repetition rate
- High laser lifetime compared to conventional discharge lamp
Depending on the selection of the specific supercontinuum laser and the application, you can use the assembly as a quasi-continuum or as a pulsed tunable light source.
