Photon etc.'s Tunable Laser Source (TLS) combines a supercontinuum source (broadband light) and a widely Laser Line Tunable Filter (LLTF). The TLS features a unique optical filtering technology that provides exceptional out-of-band rejection capabilities. This technology is crucial for the development of tunable excitation sources utilized in cutting-edge spectroscopic techniques where spectral purity is imperative. Moreover, this versatile tool is ideal for characterizing the spectral response of optics and optoelectronic devices.
Key Features
The key features of the Tunable Laser Source are:
LLTF Contrast
The LLTF Contrast acts as a filter for the tunable laser source.
LLTF Contrast - Photon etc
Applications
Characterization of dielectric thin film filters (OD of up to 12) [1]
A transmittance measurement setup using Photon etc. Laser Line Tunable Filter (LLTF) is employed to obtain spectrally resolved characterization of dielectric thin film filters with optical densities from 0 to 12 in a spectral range covering 400 nm to 1000 nm.
Time-resolved photoluminescence (TRPL) on photovoltaic materials [2]
Metastable defects in CIGS solar cells can be characterized with time-resolved photoluminescence (TRPL). TRPL is a technique where the sample is excited with a pulsed light and the luminescence signal decay is analyzed as a function of time. The excitation source is produced by combining a supercontinuum source with an LLTF (ps resolution achieved).“The developed contactless characterization method was compared with classical current–voltage measurements. TRPL leads to a more complete understanding of the physics of metastable defects in terms of quantifying the shift in minority charge carriers dynamics that it induces.”
Spectral Response of Photodetectors
The outstanding out-of-band rejection and the wide spectral range covered by the LLTF (400-1000 nm VIS, 1000-2300 nm SWIR, 400-2500 nm EXT IV) allow the precise calibration of a vast array of photodetectors including CCD, EMCCD, sCMOS, InGaAs, MCT and more. In addition to focal plane arrays, the LLTF can be used to calibrate single-pixel detectors such as photodiodes (APD, SPD, etc.), photomultiplier tubes (PMTs), or any other photosensitive device within this spectral range.
