Description
488 SLM laser diode module could be a perfect choice for Raman spectroscopy, especially for inorganic materials. Blue light lasers are widely used in surface-enhanced Raman scattering applications (SERS). Matchbox® modules are a perfect combination of high performance and low cost.

Note:
In optical systems with strong back-reflections (e.g. more than 10%), the laser must be protected by using an optical isolator with at least 20 dB isolation. Typical applications include interferometry, confocal microscopy (especially working with reflective samples), etc. Failure to comply with these requirements will render the warranty void for cases of COD (Catastrophic Optical Damage) of laser diode facets.
Fiber Termination - FC/APC (AT): 8° polishing angle minimizes back reflections from fiber tip. This is necessary especially for SLM lasers.

1 Measured with a scanning Fabry-Perot interferometer having 7.5 Mhz resolution, with scanning frequency of about 10 Hz. Interferometer testing is not provided for each laser being manufactured, the standard test is OSA measurement with 10-20 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.
