CW quantum cascade laser
L12004-2190H-C
DFB-CW drive type quantum cascade laser
A quantum cascade laser (QCL) employing SPC (single photon-continuum) and DFB (distributed feedback) structures, enables single-mode emission with continuous operation at room temperature.
By controlling the temperature with the built-in TE-cooler in the HHL package, the QCL is possible to sweep the emission wavelength without mode hopping while maintaining the single mode operation.
Features
- Light output: 20 mW min.
- Threshold current: 1 A max.
- Emission wavelength: 4.57 μm
| Emission wavelength (typ.) | 4.57 μm |
|---|---|
| Emission wavenumber (typ.) | 2190 cm-1 |
| Wavenumber sweep range (min.) | ±1.0 cm-1 |
| Light output (min.) | 20 mW |
| Threshold current (max.) | 1.0 A |
| Side mode suppression ratio (min.) | 25 dB |
| Lens | -- |
| Beam spread angle (typ.) | -- |
| Beam waist diameter (typ.) | -- |
| Package | HHL |
| Target gases | N2O, CO |

1. What are cookies?
For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors. To do this, a site will create small text files which are placed on visitor’s devices (computer or mobile) - these files are known as cookies when you access a website. Cookies are used in order to make websites function and work efficiently. Cookies are uniquely assigned to each visitor and can only be read by a web server in the domain that issued the cookie to the visitor. Cookies cannot be used to run programs or deliver viruses to a visitor’s device.
Cookies do various jobs which make the visitor’s experience of the internet much smoother and more interactive. For instance, cookies are used to remember the visitor’s preferences on sites they visit often, to remember language preference and to help navigate between pages more efficiently. Much, though not all, of the data collected is anonymous, though some of it is designed to detect browsing patterns and approximate geographical location to improve the visitor experience.
