Claim:
1. An ultrafast laser, comprising: a first optical module utilized to generate a laser pulse; a first substrate supporting the first optical module, the first substrate defining a first optical via such that the laser pulse can pass through the first substrate through the first optical via; a second optical module receiving the laser pulse from the first optical via for stretching the laser pulse; a second substrate disposed parallel to the first substrate and away from the first substrate with a first predetermined distance and utilized to support the second optical module, the second substrate defining a second optical via such that the laser pulse can pass through the second substrate through the second optical via; a third optical module receiving the laser pulse from the second optical via for amplifying the stretched laser pulse; and a third substrate disposed parallel to the second substrate and away from the second substrate with a second predetermined distance and utilized to support the third optical module; wherein the amplified laser pulse goes back to the second optical module through a third optical via disposed on the second substrate, and wherein the second optical module is further utilized to compress the amplified laser pulse for generating a picosecond or femtosecond laser output.
