Overview of Diadem IR-30: High-power Femtosecond Laser

Spark Lasers, experts in mode-locked fiber lasers, offer the DIADEM IR series of compact femtosecond (fs) lasers for optogenetics and micromachining applications.  DIADEM is a very compact, high energy ultrafast laser for advanced micromachining applications needing short femtosecond laser pulse widths.  The DIADEM-IR30 offers 40µJ of pulse energy up to 750kHz, with pulses below 400fs and rep rate capability from single shot to 2 MHz with a remarkable beam quality of M² < 1.2.  The DIADEM laser series combines the most advanced electronics for on-the-fly pulse control with a compact, user-friendly design that requires less than 5 minutes of set-up time.  The DIADEM IR has been specifically designed for demanding applications such as implantable medical device manufacturing, luxury watch manufacturing, consumers’ electronics and optogenetics applications for instrumentation and industrial 24/7 OEM working operations.


Harvard Medical School uses the DIADEM-IR mode-locked laser from Spark Lasers to facilitate cutting edge optogenetics research. To learn more about the use of these lasers for biophotonics click here.
