The new Chameleon Ultra II laser from Coherent, Inc. delivers a major increase in both tuning range and output power, compared to previous one-box ultrafast lasers.
Specifically, Chameleon Ultra II produces over 3.3 watts of output power (a 65% increase over earlier models) and produces continuous tuning over the 680 nm to 1080 nm spectral range, while similar ultrafast lasers reach only to 1020 nm. Chameleon's extended infrared performance will be a major benefit for many types of MPE (multiphoton excitation) microscopy, enabling deeper live tissue penetration as well as efficient excitation of long wavelength fluorophores.
This unique ultrafast laser is based on the existing Chameleon platform, which simplifies upgrades for both end users and microscope builders. In particular, Chameleon Ultra II maintains the same footprint, software interface, beam location and field-proven reliability as prior models. The higher power and broader tuning range result from re-optimization of the cavity optics, and the use of novel broadband mirror technology.
The Chameleon family is the only series of one-box, ultrafast lasers designed specifically to maximize the potential of multiphoton microscopy. Chameleon lasers also feature high reliability and hands-free sealed operation, in part due to their use of the long-lived Verdi pump laser.
