Products
| Product category | Description |
|---|---|
mode locking devices  |  Our customized semiconductor saturable absorber mirrors (SESAMs) can be used for passive mode-locking of fiber, solid-state and semiconductor lasers, with wavelengths ranging from 620 nm to 3.5 µm. Contact us for the optimal customized SESAM for your application. |
| Q switches | Our customized semiconductor saturable absorber mirrors (SESAMs) can be used as passive Q-switches in applications where short (max. few nanoseconds), high repetition rate and relatively low-energy pulses are required. Contact us for the optimal customized SESAM for your application. |
| saturable absorbers | Our saturable absorbers are semiconductor-based mirrors (SESAM, SEmiconductor Saturable Absorber Mirror). In contrast to bulk absorbers, SESAMs offer low saturation fluences and fast relaxation dynamics. Reflekron offers customized SESAMs for laser systems along a wide wavelength range of 620 nm to 3.5 µm, for both mode-locked and Q-switched lasers. Contact us for the optimal customized SESAM for your application. |
| semiconductor saturable absorber mirrors | Reflekron offers customized SESAMs for the volume production and development of pulsed laser systems including fiber lasers, solid-state lasers, and semiconductor lasers operating in both mode-locked and Q-switched regimes. Our SESAM designs rely on monolithic semiconductor structures fabricated by Molecular Beam Epitaxy (MBE) using GaAs, InP and GaSb-based material systems, giving access to a wavelength range of 620 nm to 3.5 µm. The nonlinearity and saturation properties of the SESAM can be accurately tailored to specific laser systems independent on the wavelength range: the nonlinear absorption can be varied from below 0.5% to over 90%, while the saturation fluences range from 10 µJ/cm2 to above 100 µJ/cm2. The relaxation time can be customized from sub-ps to ns range to fit the specific application. Contact us for the optimal customized SESAM for your application. |
