The Mai Tai HP ultrafast tunable laser is ideal for multiphoton microscopy providing more than 300 nm (690–1040 nm) in useable tuning range with over 2.5 W of average power and a pulse width of less than 100 fs. The Mai Tai series reliability is maintained using proven, ultra-stable regenerative mode-locking. Using this method, the Mai Tai oscillator is capable of hands free, drop-out free wavelength tuning enabling speedy collection of excitation profiles all at the click of a mouse. StabiLok® real-time monitoring technology also enhances system reliability by providing excellent beam pointing stability and minimal average power fluctuations, as well as eliminating wavelength drift.
