Chameleon Ti:Sapphire

Widely tunable, high power, hands-free femtosecond lasers for multiphoton imaging, ultrafast spectroscopy, and non-linear materials studies.   

With thousands of installations worldwide, Chameleon Ti:Sapphire lasers are recognized as genuine workhorses of the multiphoton imaging community. Industry leading power and tunability further expand the possibilities in other ultrafast non-linear studies. 

Chameleon Ti:Sapphire Family

A wide selection of models is available depending on your application. The wavelength coverage of Ti:Sapphire can be further extended by our range of automated Optical Parametric Oscillators (OPOs).
