The ALTAIR mode-locked fiber laser produces high average powers up to 20W, ultrashort femtosecond pulses  of <150 fs (<250 fs for VERSA configuration), at a high repetition rate of 80 MHz (others available) in an air-cooled, ultra-compact and robust package.  The ALTAIR is an ideal solution for bioimaging/biophotonics applications such as multiphoton microscopy where deep excitation of red-shifted indicators such as RCaMP, dtTomato, and MCherry is required. As a mode-locked fiber laser, the ALTAIR provides high stability and excellent beam quality.  A host of options can be added to the system such as GDD pre-compensation down to -60,000 fs^2 (lower options available), custom wavelengths, harmonics, repetition rates, and more.

The Altair Femtosecond lasers are ideally suited for multi-photon microscopy applications. The fiber-based design enables a more compact, robust, and reliable laser than its DPSS and Ti:Sapphire counterparts. Through this simplified fiber design, these fiber lasers require little to no maintenance.  Historically, researchers have been using Ti: Sapphire lasers, which utilize many more components and moving parts, including water cooling systems, requiring significantly more maintenance and ultimately leading to higher total cost of ownership.   The combination of short pulse duration and high average power offers many benefits for bioimaging such as lower scattering and deeper penetration and is the preferred solution for both OEM and researchers in the microscopy and life sciences fields
