There are some very good explanations why Jesus is not recorded as having laughed.
Jesus was likely an Essene Jew. These lived away from Jerusalem and were very ascetic - they fasted, prayed alone, immersed themselves in the ritual purification bath’s daily, had strict dietary laws and were committed to celibacy. In many ways they were the forerunners of modern-day Benedictine Monks. To this day Monks under the rule of St. Benedict are forbidden from jocularity, idle amusement or horseplay. Benedictine monks are men of great joy - they smile constantly, but you won’t see them joking around.
Another has to do with laughter in the Bible. Laughter is often portrayed in the Old Testament as an expression of disbelief or distrust.
Jews were very concerned with shame - shame was the worst thing that could happen to you. Laughter is often an expression of contempt, to laugh at someone was to shame them. Laughter was often associated with shame in the Bible. No one wanted to be a laughingstock.
I’m not saying that Jesus didn’t laugh, just that it was not recorded because of the cultural and literary reasons, how it was associated with mistrust, contempt and shame.
