Dual-wavelength picosecond fiber lasers for nonlinear microscopy

   
     

Conventional fiber lasers for CARS spectroscopy and microscopy and for SRS microscopy are large, non-mobile systems that require 30 minutes or more to warm up and additional cooling equipment, and are characterized by long tuning times of the wavelengths. The innovative thing about AFS' fiber laser sources for nonlinear microscopes is that they have overcome these operator shortcomings while providing excellent laser beam focusing quality Mē, tuning range and speed, pulse duration, repetition rate and other performance parameters.

 

The dual-wavelength ps fiber lasers from AFS are compact mobile systems (weight 15 ... 35 kg) and convince thanks to:

   
     

•

Tuneability over the entire wavelength range in approx. 2 s

•

No warm-up time

•

User-friendly control software

•

Intrinsically synchronized pulses

•

Alignment-free all-fiber frequency conversion

•

Optional fiber-coupled output systems for easier coupling with nonlinear microscopes and avoidance of disturbances

 

Coupled with nonlinear microscopes, they are used in biomedical laboratories of research institutes and companies, in hospitals and clinics during and after tumor operations and in the general biomedical examination of organic tissues, especially for

   
     

•

CARS spectroscopy and microscopy

•

Microscopic multimodal nonlinear imaging (CARS, SHG, TPEF) and

•

SRS microscopy
