Laser Diode

I am looking for a fiber coupled laser diode that can be used to mark a spot on thin flexible plastic film. The film thickness ranges from 25 microns to 100 microns and is typically used for flexible packaging of snacks, chips, rice, etc. The film may be metallic or pigmented. I need to test the marking result first. If the test is successful, I will require hundreds of units. Please provide specifications and pricing for testing.
