HTPL Lasers
Back to Lasers

  • Up to 2.6 W dot or line
  • Very high visibility
  • Focusable
  • CW and Pulsing capability
  • ESD, over-temperature, over-voltage, and reverse-polarity protection
  • Rugged industrial-grade design

StockerYale’s Lasiris™ HPTL laser is a high-power fiber-coupled diode laser capable of projecting a dot or a line. Developed for the most demanding industrial applications, the HPTL laser features fully protected diode electronics and an active air-cooling system with bipolar thermoelectric cooler – all in a compact, rugged housing. A length of optical fiber distances the diode laser from the focusing and beam shaping optics to isolate and protect the diode from harmful industrial environments.

All models can be operated as CW units or in pulsing mode by supplying an analog or
TTL signal to the connector on the laser. A fine-focusing optics module is available upon

Beam Collimators

The Lasiris™ HPTL laser can come with a collimated beam. There are presently three types of collimators available for the HPTL. Below is a table depicting the divergence of the beam in terms or the diode and in terms of two of our standard collimators.
