665nm Narrow Linewidth Single-Mode Laser Module with Tethered Head

This digital tethered laser source integrates a single-longitudinal-mode stabilized core with an adjustable tethered head, delivering a collimated open beam directly to experimental targets.

Designed for laboratory research environments, this fully turn-key digital laser system provides wavelength-stabilized performance with open-beam flexibility. Its tethered head design allows operators to maneuver the output directly to the sample or optical stage without relocating the primary control chassis.

Applications

This module is suitable for optical research, diagnostic test benches, and laboratory setups requiring single-frequency, single-spatial-mode beam delivery directly to a sample stage via a movable tethered head.

This configuration is not designed for installations requiring pre-installed fiber-coupled output, as the native output is an open beam and external fiber patch cords are sold separately.

Frequently Asked Questions

What beam profile does the tethered head provide?

The tethered head outputs a circularized and collimated open beam operating in TEM00 single-spatial mode and single-longitudinal mode (SLM).

What is the spectral linewidth of this laser module?

The system features a narrow spectral linewidth of less than 1 MHz FWHM with a typical side-mode suppression ratio exceeding 50 dB.

Does the module come with an optical fiber patch cord?

No, the unit outputs an open beam, and external fiber patch cords must be acquired separately.

What safety interlocks and controls are integrated into the unit?

The system is equipped with an emergency shut-off switch (EMO), a laser enable switch, a safety key lockout, a remote interlock port, an LED readout, and an output power control dial.
