Why a multimode fiber can not be used to realize mode-locking?

Through reviewing papers about passively mode-locking realized at 2 micron, almost everyone uses single mode fiber(such as Nufern SM_TDF_10P_130_HE) to realize mode locking? The problem is why...

Why not use an LMA(large-mode-area) fiber as the gain media when putting up a thulium-doped fiber oscillator?

Currently, I am putting up a 2 micron mode-locked fiber laser oscillator based on SESAM. However, I am encountering several problems with my experiment, My questions are as follows,First of all, I...

I want to know the difference between the conditions to realize passive mode-locking and passive Q-switching, who can tell me?

I have a SESAM and a rare-earth doped fiber (Nufern-TDF-25/400) to do experiment, actually the SESAM is from Batop, its modulation depth is about 20%, the linear cavity is used. I also use the...

Is there something wrong with the NA parameter of the Nufern's Tm fiber?

I currently calculate the numerical aperture of a 25/400 thulium-doped fiber produced by nufern. However, I do think there might be a mistake on the datasheet. Since I use the equation,...

How can I get a good fiber endface?

How can I get a good fiber end facet? I'm now use a 3SAE LCC-II fiber cleaver to cleave photonic crystal fiber, however it does not work very well, every time I cleave the fiber, I aways see some...
