Flight Crew Took Evasive Action
Environment - Non Weather Related; Procedure
Took off from Atlanta behind a 737 and shortly after airborne; just after gear up; encountered what I thought was mild wake turbulence it but triggered a stall shaker. I pushed thrust levers up and called for max thrust/spoilers in; lowered the nose and the shaker immediately stopped and conditions were stable so reduced thrust and continued.  I noticed the right engine (3A1 type - intermix aircraft) ITT turned red briefly and returned to normal with reduction. The engine ITT was discussed with dispatch and maintenance; determined to be within limits and documented in the [maintenance log] for info.  We had a frequency change to departure and did not mention the wake to ATC - I think we were just focused on ensuring navigation and EICAS indications were ok. We should have reported it; although we get similar wake experiences without the shaker quite often. Flight was continued with no further issues.Wake is nearly always a threat in ATL and other busy airports. Having mismatched engines is another; but we can't really be too mindful of it in a stall situation or windshear etc. I have pushed up thrust on the 3B1 engines a number of times for windshear etc. without seeing red. Also; be assured no one got whiplash from the thrust increase. Being one of the smaller but lower performing jets at the busy airports; I think it might be wise to use normal thrust behind 737s and 757 types (with the recat now). The other MD80 and smaller Airbus types don't seem to cause the wake issues nearly as much. Also; we always need to be ready on the controls even if autopilot is engaged.
Wake turbulence shortly after takeoff; with stick shaker activation. We were close to the ground still when this happened so an aggressive recovery was required (high engine power setting used to recover).
A CRJ-200 flight crew reported encountering wake turbulence shortly after takeoff at ATL in trail of a B737 that triggered a momentary stall warning.
