Description

532 nm SLM laser permanently fiber coupled to a multimode fiber. Ultra-stable center wavelength and good immunity to back reflections make this laser perfect for Raman spectroscopy. The small form factor allows easy integration into portable diagnostic devices.

Fiber Termination - FC/APC (AT): 8° polishing angle minimizes back reflections from fiber tip. This is necessary especially for SLM lasers.

1 Measured using HighFinesse LineWidth Analyzer LWA-10k having 10 kHz resolution. Linewidth Analyzer testing is not provided for each laser being manufactured, the standard test is OSA measurement with 20-30 pm resolution instead.

2 The output power of SLM lasers shall not be tuned and SLM performance is not guaranteed at power ratings other than factory preset. However, the power setting capability is not disabled. External attenuators are recommended instead.

3 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 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.

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

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

7  APC - Automatic Power Control.

8 SLM lasers shall not be modulated - use external modulators instead.

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

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

11 Converted from bandwidth value.
