Compact hybrid diodelaser source generates 10microjoule pulses
Scientists at IRMA America (Ann Arbor, MI) have developed a highenergy hybrid ultrafast source with potential use in practical applications that require compact sources. A distributedBraggreflector (DBR) laser diode generates electrically chirped (200ps to 2ns) pulses of 10 pJ that are amplified to 10 µJ in an erbiumdoped fiber amplifier. These pulses are then compressed to less than 2 ps with a grating pair. The laserdiode/fiberamplier source averages 100200 mW of power with 300500mW amplifier pumping.
