Ondax’s NoiseBlock ASE (Amplified Spontaneous Emission) filters suppress the broad spectrum of spontaneous emission from laser diodes to provide a pure, ASE-free, single frequency laser.
The ASE Filter is a reflective Volume Holographic Grating (VHG) with typical bandwidth of less than 150pm and throughput greater than 90%. The VHG is purposely manufactured with a slant that provides an angular separation between the specular reflections from the surface of the VHG and the filtered laser beam.
NoiseBlock filters also make excellent 90/10 beamsplitters by reflecting 90% of incoming single frequency light at a specified angle and transmitting the remaining 10%.
