Fixed-wavelength ultrafast lasers (left) and power supplies (right) are more compact than their tunable Ti:sapphire alternatives (fixed-wavelength laser and power supply are orange; tunable are blue-green). However, for two-photon microscopy, each laser technology has its advantages and disadvantages that the researcher must carefully consider.
