Altair High-power, high repetition rate Femtosecond Laser for bioimaging

Spark Lasers, experts in mode-locked fiber lasers, offer the ALTAIR series of compact femtosecond (fs) lasers for bioimaging. The ALTAIR produces high average power with ultrashort pulses (<160 fs) at a high repetition rate (80 MHz standard, others optional) in an ultra-compact and robust format.  As a mode-locked fiber laser, the ALTAIR provides high stability and excellent beam quality.  Additionally, the ALTAIR offers remarkable pulse quality at high average power with no maintenance required, by integrating state of the art high-power fully packaged fiber amplifiers and pulse management.

Femtosecond lasers are ideally suited for multi-photon microscopy applications, and lasing at 1040nm the laser offers many benefits for bioimaging including lower scattering and deeper penetration.  To find out more click here to download our white paper on how mode locked lasers are used in two-photon microscopy.
