FBH, at Laser World of Photonics Munich, will present its capabilities in diode lasers and UV LEDs and demonstrate compact live LiDAR and Raman spectroscopy. Results and advances in UV LEDs will be exhibited by FBH together with the spin-off UVphotonics. The event is scheduled from June 24-27 in Munich.
LiDAR Demonstrator: Stand-Alone, PC-Controlled Pulsed Laser Source
As part of the "Research Fab Microelectronics Germany", FBH will present a live demonstrator for pulsed laser sources, which allows flexible adjustment of pulse duration and intensity. Visitors can use a tablet to change the desired parameters and monitor the results in real time on screen. With it’s PLS flex, FBH, offers laser sources that deliver pulses in the range from 200 ps to 20 ns. The systems can be equipped with diode lasers of various wavelengths (630 - 1180 nm) and power ranges. Laser diodes, which are wavelength stabilized at 905 nm, achieve output powers of up to 100 W at ambient temperatures of up to 85 °C. This makes them ideally suited for use in LiDAR systems. FBH offers the chips in a complete development environment with driver electronics and control software.
SERDS Turnkey System in Use – For Raman Spectroscopic Measurements on Site
The compact turnkey laser system for Raman measurements is equipped with a monolithic Y-dual-wavelength diode laser, which alternately emits light at two slightly different wavelengths. The system allows very fast measurements using Shifted Excitation Raman Difference Spectroscopy (SERDS). The spectral distance of both wavelengths can be adjusted via micro heaters above the DBR gratings, which define the wavelength. If the systems are complemented with a suitable power supply, spectrometer, data acquisition and software interface, they can be used for on-site measurements. In-house developed, portable systems have already been successfully used for measurements on food, soil, plants and human skin.
