C-band frequency stabilized laser

Haoliang Optoelectronics has newly launched a 1550nm precision frequency stabilized laser (1312nm band optional), which is locked onto the atomic absorption spectrum. This series of stable frequency laser equipment is based on a unique configuration driven semiconductor laser, which has excellent frequency stability. It can be traced back to the semiconductor laser driven by it in a unique configuration, creating excellent frequency stability that can be traced back to a physical constant, thus forming a major frequency standard.

This frequency stabilized laser has the following models:

Frequency reference PFR series:

This series of low-cost desktop lasers can provide absolute accuracy and stability of+/-0.1pm that meets single frequency or long-term frequency stability requirements. The standard wavelengths are 1530 and 1550 nm, and other wavelengths can also be provided according to customer requirements. The standard output power is 2mW, single-mode, with optional SC/APC jumper output.

Narrow linewidth stable frequency NLL series:

This series of lasers adds an additional narrow linewidth mode while retaining the full performance of the PFR laser. This mode utilizes the absorption lines of the internal reference pool to reduce the linewidth of the laser diode, with typical output and optional PM, SC.APC fiber optic jumper output.There are two power modes:

LP: 2mW rated output power, 50kHz linewidth, currently only available at 1550nm;

HP: 25mW rated output power,<>

Typical features:

Original frequency reference

Excellent stability and precision

low cost

Low voice sensitivity

Optional line width<>

Optional 25mW high-power version

Typical applications:

Guangxu Instrument Calibration

Sensing

interference

Coherent optical communication

Figure 2: Spectral lines in two working modes of Clarity NLL-1541-LP: reference mode with a linewidth of 200KHz (locked at the center of the reference spectral line) and narrow linewidth mode with a linewidth of 25KHz (locked at the edge of the reference spectral line)

Figure 3: The short-term stability and long-term absolute accuracy of Clarity in Reference mode are determined by the invariant gas absorption line

C-band tunable stable frequency laser

We have recently launched a C-band tunable frequency stabilized laser, which has a built-in NIST traceable molecular absorption reference cell (H13C14N) to ensure the highest accuracy and stability of any wavelength within this range. In addition, more than 50 reference spectral lines can be locked with absolute accuracy<>
