I don't know much, but I know opamps don't create pulses. I think you need some kind of 555 circuit, but I can't help you there.

yes..i am using an astable multivibrator to trigger to a monostable multivibrator.i need to generate a 10 microsecond pulse.but when i used 741
output is distorted.i heard 741 have limitation since it is a high frequency application.so can you suggest any op amp which has same pinout as741 but in high frequency

The thread right under this one has the answers. It's marked, "help" which explains why useless labels like that are discouraged.

What will be the load and output voltage and pulse width stability/precision?

Single pulse or astable multivibrator? If astable then which frequency/duty cycle?
If monostable then how is it triggered?

A 555 will do whatever you need.

I've made a 10% duty cycle oscillator with an opamp, but not at this speed. If that will do what you want, there are rather fast opamps, but they aren't called 741. You need to be in the megahertz range to get a 10usec pulse.

Somebody else posted LMR348DR fom Digikey as able to go that fast.
