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

-----------------------------------------------------------------------------------
Can a user open the FCPA MicroJewel?
No. There are no user maintainable or serviceable parts, and there is no need to tweak the FCPA MicroJewel. Opening the the laser enclosure will void the warranty.
>> return to top
-----------------------------------------------------------------------------------
Are there any special requirements for mounting a FCPA MicroJewel?
The laser head unit must be installed (mounted) in a manner to allow the dissipation of up to 35 Watts to a surrounding ambient temperature of 25 șC. This can be accomplished by heat sinking the base of the laser head to a surface (ie. optical table or breadboard) or on stand-offs with airflow under the base.

-----------------------------------------------------------------------------------
What is the warranty period?
Each FCPA MicroJewel comes with a 1 year warranty.

-----------------------------------------------------------------------------------
What is the bandwidth from the FCPA MicroJewel?
The output bandwidth is typically ~ 8 nm.
>> return to top
-----------------------------------------------------------------------------------
Are the pulses from the FCPA MicroJewel transform-limited?
The pulses from the FCPA MicroJewel exceed the transform limit by a factor of approx. 1.5
>> return to top
-----------------------------------------------------------------------------------
Are the pulses from the picosecond version of the FCPA MicroJewel compressible? If so, to what pulsewidth?
The pulses from the picosecond version of the FCPA MicroJewel laser are linearly chirped, and are compressible to a final pulsewidth of approximately 400 fs.
>> return to top
-----------------------------------------------------------------------------------
How are the short pulses generated in a FCPA MicroJewel laser?
The short pulses are generated by passive modelocking of a Yb:fiber laser using a saturable absorber. Further compressible bandwidth in generated via nonlinear effects in a Yb:fiber amplifier.

-----------------------------------------------------------------------------------
Is there a compressor in this laser? What is it?
In the femtosecond version of the FCPA MicroJewel, the final stage is a bulk-grating compressor

-----------------------------------------------------------------------------------
What is the wavelength output of the FCPA MicroJewel?
The output wavelength is 1045 ± 5 nm
>> return to top
-----------------------------------------------------------------------------------
Is the FCPA MicroJewel laser tunable?
No. The output is fixed wavelength

-----------------------------------------------------------------------------------
What are the main applications for the FCPA MicroJewel?
Micromachining; Nonlinear microscopy (2-photon and THG); General ultrafast research.
>> return to top
-----------------------------------------------------------------------------------
What is the pulse shape from a FCPA MicroJewel (soliton, gaussian, other)?
The pulses experience self-phase-modulation combined with normal dispersion in the amplifier fiber. The final compressed pulse shape is not exactly described by any particular function, but the autocorrelation is reasonably well fit with a gaussian.

-----------------------------------------------------------------------------------
What is the beam quality from a FCPA MicroJewel?
The output from a FCPA MicroJewel is from a single-mode optical fiber and is equivalent to TEM00. Beam quality is specified at M-squared<1.5

-----------------------------------------------------------------------------------
Does a FCPA MicroJewel have a fiber-coupled delivery?
No. The output is free-space.
>> return to top
-----------------------------------------------------------------------------------
What is the polarization state coming out of a FCPA MicroJewel?
Linear, horizontal.
>> return to top
-----------------------------------------------------------------------------------
What type of detector should be used for looking at a 1050 nm pulse train?
For detecting 1050 nm pulses, a silicon PIN diode (reverse biased) gives best results.
