STB Series Saturable Absorber Mirrors (SAM) Saturable absorber mirrors are Bragg-mirrors with AlAs/GaAs quarter-wave stacks, grown on GaAs wafers with one or more low temperature GaAs (LT-GaAs) or LT-InGaAs films as saturable absorbers. Our saturable
Saturable absorber mirrors are Bragg-mirrors with AlAs/GaAs quarter-wave stacks, grown on GaAs wafers with one or more low temperature GaAs (LT-GaAs) or LT-InGaAs films as saturable absorbers.
Our saturable absorber mirrors with carrier relaxation times in the picosecond range can be used for passive mode-locking and Q-switching of diode-pumped lasers. The design of the thin film stack can be adjusted to meet the requirements of different passively mode-locked lasers in the picosecond and femtosecond region.
STB-SAM order information: Part-No description: STB-SAM-λ-A-τ-x

The resonant saturable absorber mirror (RSAM) is designated to reshape an optical signal. An optical signal which propagates in optical fibers, communication nodes and other optical devices is subject to optical losses and is modified. After every amplification stage, which uses the stimulated optical emission process, the signal to noise ratio decreases as a result of the inevitable spontaneous emission.
The RSAM, included after an optical amplifier, decreases the noise floor and allows to pass the optical pulses unaffected due to the nonlinear-optical behavior.

1.1 Free-space SANOS @ 1064 nm with One RSAM
One stage STB-FS-SANOS-1064-15ps-1
A STB-FS-SANOS consists of a resonant saturable absorber mirror (RSAM) and a conventional 100% mirror. The beam goes true the FS-SANOS without changing of the direction, but with a parallel offset of 2 mm. The RSAM has a strong non-linear reflectance. For a low input signal level the transmittance of the STB-FS-SANOS is only 2 % (98 % loss), whereas high intensity pulses are transmitted with a lower loss of 50 %. The input is isolated better than 50 dB. To meet exactly the low-intensity reflectance minimum the input beam inclination can be changed by some degrees.
Main STB-FS-SANOS data:
Resonance wavelength: 1064 nm ( 1050 nm – 1064 nm on request)
Full width at half maximum FWHM: 20 nm
Noise suppression ratio: 14 dB
Insertion loss: 3 dB
Saturation fluence: 4 μJ/cm2 @ noise suppression of 10 dB

Mirrors: one RSAM and one dielectric mirror with R > 99%, size: 4 mm x 4 mm

1.2 Two stage STB-FS-SANOS-1064-9ps-2
A STB-FS-SANOS-2 consists of two resonant saturable absorber mirrors (RSAM). The beam goes true the free-space SANOS without changing of the direction, but with a parallel offset of 2 mm. The RSAM has a strong non-linear reflectance. For a low input signal level the transmittance of the STB-FS-SANOS-2 is lower than 0,1% (99,9 % loss), whereas high intensity pulses are transmitted with a lower loss of 75 %. The input is isolated better than 50 dB. To meet exactly the low-intensity reflectance minimum the input beam inclination can be changed by some degrees.

2. Fiber-coupled Saturable Noise Suppressor
For 1550 nm wavelength we offer a fiber coupled saturable noise suppressor: FC-SANOS. It consists of a RSAM on the second port of a three port circulator and allows simple insertion into a fiber.
Fiber coupled SANOS order information: Part-No description: STB-FC-SANOS-λ-x
λ - laser wavelength
x - fiber and connector type
A SANOS is a resonant saturable absorber mirror (RSAM), mounted on a circulator. The RSAM has a strong non-linear reflectance. For a low input signal level the transmittance of the FC-SANOS is only 3% (97% loss), whereas high intensity pulses are transmitted with a lower loss of 50%. The needed peak pulse power for saturation is about 500 mW. Because the RSAM is a resonant device, the noise is only suppressed at the resonance wavelength. The common fiber connector type is FC/PC, but it can be customized. The input isolation is better than 50 dB.
Part number: STB-FC-SANOS-15XX
Resonance wavelength: 1530 nm, 1535 nm, … ,1555 nm, 1560 nm in steps of 5 nm
Full width at half maximum FWHM: 16 nm
Low intensity transmittance: 3 %
High intensity transmittance: 45 %
Noise suppression factor: 6 … 18 (dependent on the input signal/noise ratio)
Insertion loss: 3 dB
Pulse fluence: F = 100 μJ/cm2
Relaxation time constant : ~ 5 ps
Maximum mean input power: 0.5 W
Directivity: 50 dB
Fiber connector type: FC/PC, other on request
The saturable absorber without a Bragg-mirror can be used for self-starting, passively mode-locking of a laser in a similar way as a SAM, but it is working in transmission mode. It can be inserted for instance into a fiber ring laser. The saturatioon fluence of a SA is substantial higher than that of a SAM.

The resonant saturable absorber can be used for passively mode-locking of a ring laser in a similar way as a SA. But it is a resonant device with the following special characteristics:
Zero reflectance at the resonance wavelength for low intensity.
Zero transmittance for all wavelengths outside the resonance.
At the resonance wavelength increasing transmittance with increasing pulse fluence.
The saturation fluence is substantial lower than that of a SA and even lower than that of a typical SAM.
The above mentioned characteristics allow the construction of a passively mode locked fiber ring laser with
a laser wavelength fixed at the resonance wavelength of the RSA,
and low power threshold for start of cw mode-locking.
