633 NM SLM LASER (VBG DIODE; MM FIBER)
描述
Single-longitudinal mode (SLM) 633 nm laser is a replacement for HeNe, where high coherence length and exact center wavelength is needed. This wavelength is also quite popular in Raman spectroscopy. Small footprint and +5VDC (USB typical) operating voltage is exactly what's needed for handheld portable devices. Integrated precission driver electronics ensures low-noise and very stable operation throughout wide temperature range. 633 nm red radiation features average photon energy. VBG technology delivers a low cost solution to sophisticated Raman spectroscopy and various metrology needs.

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.
Note: Product specifications are subject to change without prior notice to improve reliability, function or design or otherwise.
