Does a Femtolite have fiber delivery?
The B-4-FC model has fiber delivery, but in general, the Femtolite models have free-space output.

-----------------------------------------------------------------------------------
Is the Femtolite all in one box?
The Femtolite is made up of 2 boxes, an optical head and an electrical controller. These parts, plus 2 cables for power connections are included in your Femtolite purchase.

Where can the Femtolite be serviced?
The Femtolite is generally serviced at its manufacturing site.

Are there any user maintainable / serviceable parts?
No. There are no user maintainable or serviceable parts.

-----------------------------------------------------------------------------------
Can a user open the Femtolite?
No. There are no user maintainable or serviceable parts, and there is no need to tweak the Femtolite.
Opening the laser enclosure will void the warranty.

Are there any special requirements for mounting a Femtolite?
For operation between 15 deg C and 30 deg C, there are no special requirements for mounting a Femtolite.

-----------------------------------------------------------------------------------
Which units can be fiber coupled?
Only the B-4-FC comes with fiber-coupling standard.

-----------------------------------------------------------------------------------
What is the fiber used for fiber-coupled versions?
Generally, we use SMF-28 fiber for fiber delivery.

-----------------------------------------------------------------------------------
Is the fiber used for fiber-coupling PM?
We can use PM fiber for the fiber delivery cable, as an option.

-----------------------------------------------------------------------------------
What is the pulse shape from a Femtolite (soliton, gaussian, other)?
The femtolite uses high-order solitonic pulse compression in the amplifier stage to achieve pulsewidths of 100-180 fsec. The resulting pulses at 1560 nm consist of a high-order soliton superimposed on a dispersive-wave pulse with longer duration (~300 fs).

-----------------------------------------------------------------------------------
What is the beam quality from a Femtolite?
The output from a Femtolite is from a single-mode optical fiber and is equivalent to TEM00. Beam quality is typically M-squared<1.2

-----------------------------------------------------------------------------------
What is the typical timing jitter from a Femtolite?
Timing jitter is typically < 300 fs integrated over a frequency range of 100Hz - 1 MHz.
>> return to top
-----------------------------------------------------------------------------------
What range of THz frequencies can be generated using a Femtolite?
Using an A-20-SP or AX-20 (typical pulse duration is 150 or 100 fs) the bandwidth of THz output that can be generated is a few THz (up to 3 THz)
>> return to top
-----------------------------------------------------------------------------------
What is the polarization state coming out of a Femtolite?.
The polarization state from a model A or C Femtolite is vertical, relative to the head. From a B model, the polarization state is horizontal.

-----------------------------------------------------------------------------------
What type of detector should be used for looking at a 1560 nm pulse train?
For detecting 1560 nm pulses, an InGaAs PIN diode (reverse biased) gives best results.

-----------------------------------------------------------------------------------
What type of detector should be used for looking at a 780 nm pulse train?
For detecting 780 nm pulses, an Silicon PIN diode (reverse biased) gives best results.
