LBTEK-Narrow linewidth semiconductor laser

Product Description

Ultra-narrow linewidth: <100 kHz
Mode-hop-free tuning range ≥20GHz
Free-space output / fiber-coupled output

LBTEK's narrow linewidth semiconductor lasers utilize ultra-narrowband interference filters as frequency-selecting devices, narrowing the laser linewidth through a cat's eye structure reverse self-collimating resonant cavity. Because the mode selection and feedback devices are independent of each other, compared to grating feedback mode-selection lasers, they offer advantages such as long lifespan, narrow linewidth, compact size, strong anti-interference capability, stable frequency, and a wide selectable wavelength range. They are widely used in fields such as precision interferometric measurement, atomic frequency standards, optical communication, laser gyroscopes, and precision spectroscopy physics. For special customization needs, please contact LBTEK customer service. The 780 nm/852 nm narrow linewidth semiconductor laser is a Class 3A laser device. Please avoid direct eye exposure to the laser during use.

Narrow linewidth semiconductor laser

Precision wavelength tuning <1MHz
Frequency stability <1%
Free-space optical output

The narrow linewidth semiconductor laser series adopts an integrated mechanical structure combined with atomic spectral line frequency stabilization technology, ensuring that the output wavelength is precisely locked to specific atomic transition lines (852nm/780nm). Through a high-bandwidth active feedback mechanism, deep suppression of laser frequency noise is achieved, ensuring long-term continuous locking stability. The ECDL series features ultra-narrow linewidth (typical value <100kHz), power output stability <1%, and supports a mode-hop-free continuous tuning range of ≥20GHz. The laser beam quality is excellent, with fast and slow axis divergence angles less than 1mrad and 4mrad respectively, and a 30dB isolator ensures the purity of the optical system.
Note: The 30dB isolator is an optional accessory and can be ordered separately based on system requirements.

Fiber-based narrow linewidth semiconductor laser

Precision wavelength tuning <1MHz
Single-mode polarization-maintaining fiber output
FC/APC fiber optic interface

This fiber-coupled narrow-linewidth laser delivers 1-28mW high-stability frequency-stabilized light through a single-mode polarization-maintaining fiber (5µm core/FC-APC). It maintains an ultra-narrow linewidth of <100kHz, mode-hop-free tuning of >20GHz, and atomic line locking capability. An optional 30dB isolator accessory ensures polarization purity and system stability. Designed for plug-and-play solutions in precision applications requiring long-distance transmission, such as quantum technology and coherent sensing.
Note: The 30dB isolator is an optional accessory and can be ordered separately based on system requirements.
