Semiconductor Saturable Absorber Mirrors

Our institute specializes in the development and manufacture of Semiconductor Saturable Absorber Mirrors (SESAM) using advanced molecular beam epitaxy techniques, utilizing group III-V semiconductors. As a core component in DPSS passive mode-locked lasers, SESAMs have revolutionized the field by enabling ultrafast pulsed laser technology. Our research and development efforts are dedicated to overcoming the challenges of extending SESAM technology into the mid-infrared (MIR) region.

Short infrared SESAMs have already demonstrated significant success in various applications, including telecommunications, medical imaging, and material processing. However, the mid-infrared region presents unique opportunities and challenges. MIR SESAMs are nonlinear light-absorbing structures that integrate a mirror with a saturable absorber, enabling the generation of ultrashort pulses necessary for advanced microfabrication and spectroscopy.

Our Optoelectronics Department is equipped with state-of-the-art facilities and expertise to push the boundaries of SESAM technology. By leveraging our molecular beam epitaxy capabilities, we can design and fabricate custom SESAMs tailored to specific requirements. Our solutions cater not only to short infrared applications but also to the burgeoning demands of the mid-infrared spectrum. With the increasing need for ultrashort pulses in various industries, our SESAMs are poised to meet and exceed these demands, driving innovation and performance in next-generation laser systems.

Partner with us to advance the development of SESAM technology, whether for cutting-edge research or commercial applications. Our commitment to excellence ensures that we deliver high-quality, reliable SESAMs that pave the way for new breakthroughs in ultrafast laser technology.

Our capabilities allows us to developed SESAM mirrors for the 760 nm – 15000 nm range and they can be mounted on AlN, copper or kovar custom made mountings – heat sinks.
