Laser diode beam sources of type 51nanoFCM-… have reduced power noise, reduced coherence length and low speckle contrast as a result of the internal RF modulation. The laser diode beam source 51nanoFCM-… can be used for atomic force microscopy (AFM) and as a pilot laser during alignment applications.
Performance Features:
- Spectral range 405 nm to 1550 nm
- Laser output power up to 30 mW
- Noise <0.1 % RMS (<1 MHz)
- Output power adjustable with potentiometer or external voltage control input
- Modulation inputs for analog and TTL control (up to 100 kHz)
- Operation mode: constant power
- Coherence length 300 µm
- Beam profile is rotationally symmetric with Gaussian intensity distribution
- Singlemode fiber cable or polarization-maintaining singlemode fiber cable (polarization aligned to connector key index)
- FC-APC connector (8°-polish), optional DIN AVIO, ST or E-2000
- Fiber cable with strain relief and protective sleeving (Ø3 mm)
