  • Picosecond MOPA Lasers

LASALLE, Quebec, June 30, 2010 — A family of fiber-based master oscillator power amplifier (MOPA) lasers has been introduced by Genia Photonics. They deliver short, high-frequency pulses in the picosecond regime and offer quick and easy access to all the key laser operating parameters. Applications include micromachining, etching and ablation.

The graphical user interface (GUI) makes the unit easy to set up and operate, while providing full control of all the operating parameters.

There are no moving parts to wear down and no free-space optics to be aligned. The design offers a choice of a fixed- or a variable-wavelength seed source that combines with a chain of amplifiers into a compact unit available in either a tabletop or a 19-in. rack-mount configuration. The system uses an optical-fiber output that keeps the light guided up to the target, and the fiber-based platform enables the unit to be easily and reliably transported to where it is needed.

Plug-and-play operation makes it simple to install and use under the control of an ordinary PC, and the accompanying GUI provides the user with an easy way to control the laser's configuration and operation. It also provides a clearly visible indication of laser status.

The MOPA's output power, pulse frequency, pulse duration and pulse energy are all user-configurable during operation, but customers must specify the range for these parameters at time of order. Output maximum average power options include 100 mW, and 1, 5, 10, 20 and 30 W. Pulse width options can be either a fixed value from 20 through 500 ps, or a variable range of either 20 to 40, 40 to 150 or 150 to 500 ps. And pulse repetition rate ranges can be selectable from within the 100 kHz to 200 MHz range.

Several additional options are to be specified at time of order. Operating wavelength can be set anywhere in the ranges of 1030 to 1080 nm or 1530 to 1565 nm, with other wavelengths available upon request. A variable-wavelength option is also available. Linear polarized output, rack-mount configuration and a synchronized trigger output signal are options as well.
