Fiber Laser Bandpass Filter

Our premium bandpass filters are hard coated for higher transmission and are more durable and longer lasting than our standard bandpass filters.

Fiber laser bandpass filter.

It is used to block out unwanted noise signals in edfas and fiber laser systems. This would allow measurements from the uv to the nir range to be taken. The components are characterized with high isolation low insertion loss high return loss excellent environmental stability and high power handling capability. The highly reflective side of the filter should generally face the source minimizing the thermal load on the blocking glass and epoxies.

Applications include sideband noise suppression in erbium doped fiber amplifiers edfas and for use in tunable laser transmission systems. Bandpass and laser line filters are available in the visible near ir and infrared ranges. This advantage is accompanied by a loss of transmission of approximately 20 30. Newport s tunable bandpass fiber optic filter is used to adjust the center wavelength of a narrow passband within a 30 nm range around 1550 nm.

Our bandpass filters feature a dielectric stack fabry pérot interferometer design. All standard laser line filters can also be delivered blocked. It is used to block out unwanted noise signals in edfas or fiber laser systems. Adjustment of the center wavelength is accomplished by tilting the bandpass filter with a high precision micrometer.

The bandpass can be varied from 2 nm to 18 nm and the center wavelength can be tuned from 1525 nm to 1560 nm. Sensitivity to angle of incidence. 1550nm band pass filter 1 5μm components for fiber laser the 1550nm band pass filter is a micro optics device based on environmentally stable thin film filter technology. Unblocked standard laser line filters blocking area with 0 85 1 15 x cwl have a transmission of 60 85.

Manually tunable optical filter dicon s manually tunable optical bandpass filter is used to manually adjust the center wavelength of a narrow optical bandpass filter over a 30nm wavelength range centered at 1550nm. Narrow 0 8 nm bandwidth. Bandpass imaging filter in ball lens is simple and widely tunable based on frustrated total internal reflection a tunable filter is compact has a large range and can be easily designed into optical systems. A bandpass filter is characterized by a defined passband onto which cut off regions are connected on both sides.

It consists of two multi cavity thin film filters with 18 nm bandpass with very steep walls.
