532 NM SLM LASER (DPSS; PM FIBER; 50mW)
描述
Green single-frequency laser at 532 nm is one of the most important lines for Raman excitation. A very narrow spectrum combined with good beam quality makes this laser perfect for scanning micro Raman applications. The 532 nm SLM laser is a very compact DPSS module for portable diagnostic applications, RGB holography, as well as various scientific setups. The module contains a powerful Peltier cooler, microprocessor-based electronics, a USB control interface and many useful accessories for ease of integration. In portable applications, this laser can be powered from conventional USB power banks. For fiber delivery, please check MM, SM, PM fiber output options. Higher output power is available on request.

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.
