0783L-21A-NI-NT-NF

產品型號：0783L-21A-NI-NT-NF
產品說明：

783 nm SLM laser is designed for Shifted Excitation Raman Difference Spectroscopy (SERDS). This laser is used together with a 785 nm as a matched pair of identical excitation sources having central wavelength peaks separated by 2 nm apart. This separation is quite universal and suitable for most spectrometers. It is recommended to combine the two laser beams into a single optical path using a polarizer and then apply the laser lens clean-up filter. Another approach is to use Volume Bragg Grating based filters for coupling the beams together and cleaning-up the lines at the same time.

*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 Beam width and height are measured at 0.45 m from output aperture.
*7 For lasers without integrated optical isolators.
*8 Break-out-boxes AM-C8 and AM-C3 can be used for conversion of UART communication to either USB or RS232.
*9 TTL digital modulation up to 10 MHz.
*10 Excluding control interface pins and an output window/fiber assembly.
*11 Whichever occurs first. The laser has an integrated operational hours counter.
