The LCS-DTL series of diode pumped solid state lasers delivers excellent performance from a low cost compact rectangular package and external power supply. Outputs are available in the green and infrared with powers in the 10mW - 1W range.
The laser head includes a built in bipolar Peltier thermo-electric cooler for the laser pump diode and also for the frequency doubling crystal (where present). Active temperature control circuitry ensures that optimum conditions for both the pump diodes and the frequency doubling optics are maintained inside the head itself. This allows the laser parameters to be stabilised and provides an output stability of better than 2% per hour. One important feature of the LCS is that the output power is also stabilised using a closed loop feedback circuit. As a result, highly stable output power of variation less than ±1% is achieved across a wide operating temperature range (15-35°C), automatically.
The laser head is provided with a single phase 240VAC power supply unit. The internal circuitry contained within the power supply protects sensitive components inside the laser from surges or spikes in the mains voltage that would otherwise cause them damage. The power supply unit also provides additional features enabling the output power to be adjusted over the full operating range of the laser. Each LCS-DTL laser has a key switch (on/off), emission indicators, a manual beam shutter and a remote interlock. All CW laser systems have fully adjustable output power. The laser output can be controlled manually from zero to the maximum value specified for laser model, or via remote interlock by means of a control voltage. The front panel of the power supply also features a digital readout detailing the laser output power. In addition there is also the opportunity to modulate the laser output by means of external triggering signal through the remote interlock. Computer control via RS232 is also available.
