Multiphoton microscopy is a powerful and versatile technique, applied in numerous fields in biology, such as neurology or embryology. It relies on an ultrafast laser to excite fluorescent molecules or proteins. t-Pulse is an ideal excitation source for multiphoton microscopy. In addition to its small size and ease of use, its infrared wavelength minimizes autofluorescence, scattering in biological tissues and cell toxicity.

Micromachining. Femtosecond lasers have gained wide recognition as a versatile and high quality tool for micromachining and laser ablations. Two major features have proved essential for quality micromachining:The high peak power allows machining of virtually any material, including copper, glass, ceramics, which are often difficult to process with lasers.The ultrashort pulse duration eliminates thermal effects, often responsible for unwanted features such as microcracks, molten debris.

Trace element analysis is the detection and quantification of minute traces of chemical elemnts within a sample, which provides essential data for environmental sciences (for example contamination by heavy metals), or geology.The method, named femtosecond LA-ICP-MS (Laser Ablation - Inductively Coupled Plasma Mass Spectrometer), involves removing, with a pulsed laser, a small quantity of the sample to be analysed. The particles generated are then ionised by a plasma, and analysed in a mass spectrometer.

Medical devices. For the most demanding applications, ultrafast lasers offer unmatched benefits: They can process virtually any material without any heat dissipation, and therefore with an extremely high accuracy and quality. They are now available with a high average power for high productivity, and excellent industrial reliability. Among typical applications, they can cite the manufacture of a new generation of bioresorbable, nitinol or polymer coronary stents, fine processing of catheters, or surfact texturing of bio-implants.

Pump-probe techniques using ultrafast lasers measure events on picosecond time and are applied in such diverse fields as ultrafast spectroscopy, photo-acoustics, TeraHertz imaging, etc.
This technique is very efficient for small measurement ranges, but may lead to a long acquisition time for longer ranges. The t-Pulse and Mikan ultrafast oscillators are efficient laser sources for this application.
