You can buy laser diodes and build your own but they're "notoriously fussy" (per ref. 1). Also check out ref 1's link to the Sam Goldwasser laser info (ref. 2).

i have a cheap 40cent (US) laser pointer that came with the lighter. battery included. i dont know where its made. mabe in korea or china...
components:
1 laser diode
3 button cell 1.5V batteries.
i wonder how much money they used to manufacture such a cheap thing... we import them here, yet they're still so cheap.
