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) |
|
 |
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 |
|
 |
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.
