Max Planck Institute chooses laser source for microscopy experiments

The Max Planck Institute for Biophysical Chemistry is using Mobius Photonics' G1R2 laser source in the former's super-resolution microscopy experiments.

The Mobius G1R2 was customised for the Institute's needs to produce a comb spectrum of user-selectable visible wavelengths with about a 1ns pulse duration and a 20MHz repetition rate. The Institute's experiments demonstrated that a laser-based fluorescence microscopy technique called stimulated emission depletion microscopy could image intact living multicellular organisms. 

Mobius technology vice president Manuel Leonardo said: 'Building on our experience in super-resolution microscopy Mobius has recently developed a new prototype laser that offers similar capabilities to our G1R2. Called "Rainbow" the current prototype generates five discrete wavelengths.'

Rainbow produces output at 557nm, 571nm, 585nm, 600nm and 616nm. Like G1R2 it has 1ns pulse durations at repetition rates of up to 20MHz and pulse energies ranging from 25 to over 50nJ per pulse, depending on the wavelength.
