The DTL series are benchtop CW, air-cooled lasers that emit in the green or infra-red spectral regions. Output powers are wavelength dependent and lie in the 20-2000mW region.
These lasers provide excellent beam quality and power stability from a compact and easy to use turnkey system at an entry level price.
Electrical modulation of these lasers is possible, but only at very low frequencies and is not advised.
DTL series lasers have a 12VDC power supply and a simple benchtop controller. The benchtop controller works with a Windows PC running the LCC-300 laser application software (included). The PC settings are stored in the non-volatile memory of the controller. The software allows control of the laser output (simple on/off control), output power adjustment, and provides a read-out and recording capability of the laser parameters. The controller also has an interlock point.
Amplitude stability is dependent on short term noise and longer term drift. All of our lasers in the DTL series are available with average power stability rated at <2% over 8 hours at the specified operating temperature range and with adequate heatsinking, after warm-up. Amplitude noise is less than 1% RMS.
The beam quality of these lasers is excellent. They deliver a circular, TEM00 spatial mode with an M-squared of 1.05-1.3, wavelength dependent. The beam pointing stability of these lasers is also extremely good, typically <0.01 mradians/ °C after warm-up. The polarisation of the output power is 100-1.
The dimensions of the laser head are detailed in the data sheet.
These lasers are designed for lab use. They are also suitable for incorporation into such OEM systems where they can be maintained or replaced easily at scheduled and unscheduled service intervals. These lasers are not designed for operation in harsh temperature, humidity, or electrical environments or for exposure to high loading stress, acceleration, shock or vibration. Please note that the failure to provide adequate cooling may result in the premature failure of DPSS lasers.
