Basics

  • This page explores simple off the shelf componets for lasers and their associated optics

Small Lasers

  • 3.5W $100 5-9 business days - [1]
  • 5.5W complete - $100 - China ship - [2]
  • 3W - $57 - [3]
  • 3W $60 - [4]
  • 6W- no electronics - $99 - [5]
  • 2.5W - 6-13 day ship - [6]

10-100W

  • 15W $102 - [7]
  • 15W $120 - [8]
  • 10W $169 - [9]
  • 14W peak - $230 - [10]
  • 15W - $330 with power supply - [11]
  • 10W - $239 - [12]
  • 20W - laser diode bar, no power supply - [13]
  • 30W fiber coupled laser diode with fiber and no collimator - $350 - [14]
  • 50W used 808 nm bar only $540 - [15]
  • 50W C02 - $134 - [16]

15W Lasers

  • $300 - [17]
  • $100 - the $100 ones appear to be fraud

Collimators

Device that takes incoming light waves and makes them parallel. See [18]

  • 10W max - $57 - [19]

Uses

  • 20W fiber laser cuts 0.2 mm steel and 0.4mm copper and aluminum - [20]
