Description

Compact 1123 nm laser is a DPSS module used in numerous applications, such as inspection, optical guiding, infrared absorption. This laser is coupled with single-mode polarization-maintaining (PM) fiber. The small size and all-in-one concept of the MatchBox series make the laser ready for integration into portable handheld devices. High long-term power stability is ensured by TEC thermal stabilization, as well as thermal and optical feedback.

By default, this type of laser is built with FC/PC connector, but other fiber terminations are available upon request. Details about non-standard connector and the fiber used with it should be discussed with the Integrated Optics sales team.

Fiber Termination - FC/PC (PT): FC/PC has good insertion repeatability, therefore is often used in single-mode fiber applications. Features a key for polarization-maintaining fiber installations.

¹ The optical power can be tuned from virtually 0% to 100%. However, other specifications, such as central wavelength, power stability, noise, polarization ratio, beam shape, quality and circularity are not guaranteed at power levels other than factory preset power. Significantly worse power stability is to be expected at very low power levels, e.g. <3% from specified nominal power.

² The long term power test is carried out at constant laser body temperature (+/-0.1 ‎°C) using an optical power meter with an input bandwidth of 10 Hz. The actual measurement rate has a period of about 20 seconds to 1 minute.

⁴ Noise level is measured with a fast photodiode connected to an oscilloscope. The overall system bandwidth is from 2 kHz to 20 MHz.

⁵ With possible error of up to ±5°.

⁶ Break-out-boxes AM-C8 and AM-C3 can be used for conversion of UART communication to either USB or RS232.

⁷ Excluding control interface pins and an output window/fiber assembly.

⁸ Whichever occurs first. The laser has an integrated operational hours counter.
