Laser crust | |||||||||||||||||
Although a microwave oven is very energy conservative it cooks by evenly heating moisture content of the food which results in a crustless and frequently soggy final result. Some microwaves supplement the normal heating with a grill which is much more energy wasteful and causes spatter which demands post cooking cleaning. I wonder if a high power laser with a revolving mirror system could create a crust using less energy and a quicker final result.

I think it would. They're very efficient because they just heat the subject, not the air.
Just the cost of high-power lasers is such an issue. I'm sure at some point, we'll use them instead of Xacto-knifes, but right now, no way.
Probably would take some careful development to make them actually brown to the depth and color we expect, rather than burn a pattern of 0.001 inch-wide tracks across the top. Also would have to recognize the exact location of the item, else it would be burning the inside of the oven's paint.
Might be useful for commercial production, but not home use, unless the Chinese are ahead of me.
I make a grilled cheese by toasting the bread in a toaster, and then a quick microwave to melt the cheese. No frying pan to clean.
