DSEA CW Fiber Amplifier with a Frequency Doubler
OVERVIEW
Input wavelength/Output wavelengths: 1550–1560 / 775–780 nm
Custom Wavelengths: Any within the range 770 – 785 nm
Output Power: Up to 2 W
DSEA is a product line of Erbium fiber amplifiers equipped with a frequency doubler unit. These amplifiers deliver maximum output power up to 2 W (free space output) or up to 1.5 W in a fiber-coupled version. These models are intended for use along with the different seed lasers including single-frequency seeders with an output power range of 0.1 – 1 mW ( 10 – 0 dBm) or 1 mW – 50 mW (0 – 17 dBm).
FEATURES
SHG PHASE MATCHING TEMPERATURE TUNING
DSEA allow for the Second Harmonic Generation Crystal/Waveguide Mixer for SHG Phase Matching Temperature tuning according to the seed-laser set wavelength.
OUTPUT POWER ADJUSTMENT. APC/ACC MODES OF OPERATION. OUTPUT POWER STABILITY.
This laser model allows for output power adjusting in the range of 10 – 100 % of the nominal output power. The amplifier can operate in Automatic Power Control (APC) as well as in Automatic Current Control (ACC) modes. These amplifiers provide excellent long term power stability.
OPTICAL OUTPUT TYPE
DSEA provides a free space output from the laser head. It also can be equipped with a fiber port or a Waveguide Mixer for SHG with a fiber output for fiber coupling.
COMPUTER CONTROL
The standard DSEA model allows controlling the laser using a computer via a USB port. The original Optromix
software is provided along with the laser.
