The Spectra-Physics® Mai Tai® SP ultrafast laser is the ultimate short-pulse oscillator with an unprecedented level of automation and long-term environmental stability. Designed for seeding ultrafast amplifiers, the Mai Tai SP laser is capable of producing a broad range of output bandwidths: 60 nm to 10 nm, corresponding to near transform-limited pulse widths from <25 fs to 100 fs. The bandwidth is user-adjustable via the Mai Tai SP graphical user interface (GUI). This unique feature allows for seeding sub-35 fs, 120 fs, and 2 ps amplifier systems using the same seed laser without manual realignment. Also adjustable via the GUI is the center wavelength from 780 to 820 nm.The Mai Tai SP has exceptional long-term environmental stability. It is built on the proven Mai Tai laser platform with the largest installed base of ultrafast lasers in the industry. These lasers utilize StabiLok® active beam alignment technology, EternAlign permanent optics mounting technology, a temperature-stabilized housing and active purge technology to ensure long-term stability under widely varying environmental conditions. The Mai Tai SP uses ProLite diodes, field proven leaders in diode reliability and lifetime producing uninterrupted output for >40,000 hours.
