Kasper Schmeichel has revealed that he told the referee that he was being lasered in the face prior to Harry Kane's penalty.
It comes after the Tottenham striker saw his spot-kick saved by the Denmark stopper, though he was on hand to knock in the rebound.
That gave England the victory they craved to set up a Euro 2020 final against Italy on Sunday night at Wembley.
It came during a dramatic clash on Wednesday which saw the Danes go ahead after 30 minutes when Mikkel Damsgaard beat Jordan Pickford with a sublime free-kick.
The Three Lions came back soon after when Bukayo Saka's low cross was diverted into his own net by Simon Kjaer.
That was enough to take the match to extra-time which saw Raheem Sterling fouled in the box and allowed Kane the chance to score from the penalty spot.
But there was controversy as a laser pen was spotted shining on Schmeichel's face, which has led to a UEFA investigation.
And the Leicester star has admitted that he spoke to referee Danny Makkalie about an earlier incident in the match.
He said: "I did not experience it on the penalty kick because it was behind me on my right side. But I did experience it in the second half.
"I told the referee. And he went to say something to the other officials."
Though Denmark are disappointed at crashing out of the semi-finals, their country can take a lot of heart from their extraordinary run.
After Christian Eriksen's cardiac arrest on the pitch in the opening match, Kasper Hjulmand and his players showed how together they are as a team.
Schmeichel added: "I think the best memory I have is just of this team and of this country.
"Just the togetherness and the fact we’ve been together for nearly six weeks and we’re still not ready to say goodbye is very telling.
"We’ve always said playing for this country is very special to us and it certainly hasn’t changed.
"The support we’ve received, we’ve said it numerous times, you just don’t experience that very often in life and it’s certainly something we’ll take with us."
