CL-L DPSS lasers are low noise, benchtop CW, air-cooled 532nm green lasers. Output powers are in the 25mW - 500mW region.
These lasers provide excellent beam quality and power stability from a compact and easy to use turnkey system at a mid-range price level.
Long-term amplitude stability is <2% (over 8 hours). Super stable options are available (<0.5% and <0.25% over 24 hours). The amplitude noise of these lasers is low, <0.5% from 10Hz to 20MHz. As the linewidth of these allows several longitudinal modes to oscillate, the coherence length is relatively short and may be unsuitable for some applications. For applications requiring long coherence length, please see the single mode lasers. The beam pointing stability of these lasers is very good, typically <0.02mradians after warm-up.
In their standard configuration, they provide constant output power without modulation. However, analogue and digital TTL modulation capability are options.
A power supply that matches the laser head is provided as standard. This includes key switch and interlock. An optional upgrade to the CL2005 power supply also gives you manual output power adjustment and front panel indication LEDs. The power supply can also be provided with an RS232 interface for remote laser operation. An optional 12V DC power supply is available.
Options: - Higher amplitude stability options down to 0.5% and 0.25% amplitude variation over 24 hours. - Multimode, singlemode, or polarisation preserving fibre coupling option - External TTL modulation and external analogue modulation options - External analogue output power control - RS232 remote control - 300:1 polarisation option (model dependent) - Built-in custom beam expansion optics
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.
