Here is my circuits, simple, yet, when I disconnect the MOSFET and

everything else is correct. After I connect the mosfet and load (here
I didn't use a laser diode, in stead I use a 1 ohm power resistor),
all 're in a messy! MOSFET is hot coz it's not fully on, square wave
form contains a lot of ringing, overshoot, duty cycle? no duty cycle
but some weired square waves with spikes.

It is a very common circuits but I wonder something wrong?

IXDD414 bypassed enough?

I've never had a problem with the IXDD414..
