488 NM SLM LASER (VBG DIODE; MM FIBER)
描述
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 2 modules are a perfect combination of high performance and low cost. This laser is fiber coupled to a 105 µm MM fiber.

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 SLM lasers shall not be modulated - use external modulators instead.
7 Excluding control interface pins and an output window/fiber assembly.
8 Whichever occurs first. The laser has an integrated operational hours counter.
