Mobius Photonics has devised a unique prototype fiber-based laser source called Rainbow for ultra-resolution microscopy purposes. The laser source produces visible-wavelength and user-switchable laser pulses.
The high-repetition-rate, short-pulse laser system, Rainbow now generates output at 616 nm, 600 nm and 585 nm. The individual wavelengths of the system can be altered immediately, enabling end users to customize the fluorescent marker’s input in a specific application. Based on the selection of the wavelength, the pulse energies of the system will vary between 25 nJ and more than 50 nJ per pulse.
At a repetition rate of as high as 20 MHz, Rainbow has nearly 1-ns pulses, resulting in a laser system for ultra-resolution image production with rapid acquisition times. The system is air-cooled and has a small laser head to simplify incorporation with microscopy systems. Its modular design facilitates upgrading of systems, field servicing and integration.
According to Kiyomi Monro, the Chief Executive Officer at Mobius Photonics, the company’s technical team has designed a unique method of utilizing fiber to produce visible wavelengths for exciting the exhausting fluorescence and the fluorescent markers in ultra-resolution microscopy purposes. The prototype design can now produce three important wavelengths and the company has plans to expand the functionality of the Rainbow system to produce up to seven distinct wavelengths from 557 to 651 nm.
