TTL or Analog Modulation

TTL or Analog Modulation

Our normal lasers have a continuous wave (CW) normal working mode. For modulation mode, there are 3 kinds of methods: direct intensity modulation (TTL or analog), AOM and shutter. The direct intensity modulation rate is available for 2 kHz, 5 kHz, 10 kHz, ...   30 kHz; AOM is with high modulation rate 1 MHz; Shutter is with repetition rate maximum 10 Hz. CNI is available for customized product on customers' requests.

◆Direct Intensity Modulation
    TTL modulation: Frequency is optional for 2 kHz, 5 kHz, 10 kHz...30 kHz upon request.
    Analog modulation: Frequency is optional for 2 kHz, 5 kHz, 10 kHz...30 kHz upon request.
                                    Voltage is optional for 0-5 volts DC input for regular products.
                                    Other choices are available upon requests, such as 0~4.5 volts DC, 1.0~4.5 volts DC and so on.

AOM (Acousto-optic Modulator)

AOM(Acousto-optic modulator)

It belongs to the high-speed acousto-optic pulse modulator which realizes the intensity modulation over the laser according to the inputted pulse signal and gets corresponding digitally coded optical signal by inputting the digital signal of different codes and frequencies (TTL level) into the driving power supply of modulator. It is mainly used in such fields as laser text-image processing and laser digital communication.

This product has such characteristics as quick modulation rate, small volume, high efficiency, high extinction ratio, easy coding and convenient use
. CNI can provide high frequency modulated DPSS lasers: single longitudinal mode lasers and high power stability lasers, wavelengths are available for 473nm, 532nm, 556nm, 561nm, 671nm, etc.


Shutter

Shutter

Low cost mechanical shutter, with repetition rate maximum 10 Hz. The valid output power is up to 3W available. The rise and fall time can be lower to 0.7 ms. Delay time is minimum 5 ms.
