Q1是一款紧凑, 节能, 半导体泵浦, 风冷型Q开关激光器，可广泛适用于需要高峰值功率脉冲的应用场合。
激光器可在10Hz重复频率下产生高达45mJ的脉冲能量或在50Hz重复频率下产生高达10mJ的脉冲能量。激光束发散度低使其配合H1系列谐波发生器模块可有效转换为谐波波长。
激光器可配置为单独通过Nd:YLF晶体发射1053nm波长的激光或通过Nd:YAG晶体发射1064nm波长的激光。
由于Nd:YLF晶体的无热化特性，使得激光器在1053波长下，从单发脉冲提升至最大重复脉冲频率而不会发生明显的发散角或光斑轮廓变化。
创新的激光器设计方案人性化的整合性系统使得激光器几乎无需维护。
没有额外的水冷装置和笨重的电源系统占用额外的空间。
激光器元件高度集成化在一个腔体内，外部只有一个集成了控制界面和12VDC电源适配器的轻量化控制盒。激光器总重量不超过5kg。
激光器通过内置服务器经以太网端口进行监控。电脑手机与浏览器均可用于控制Q1。作用于用户设备的低抖动触发脉冲可提供300µs的内触发模式。在外触发模式下,激光脉冲可由延迟发生器外部触发。并提供可用于与用户设备集成的API。
可通过多种可选附属设备进一步扩展激光器功能：
> 通过单独的H1系列谐波发生器最高可输出五次谐波
> 通过作用于基本波长激光束的电动衰减器可对脉冲能量进行调整
> 通过具备模拟和/或数字输出的附加脉冲能量监视器可对脉冲能量进行监测
> 提供光纤耦合输出定制服务。详细规格请联系咨询。

1）Due to continuous improvements all specifications are subject to change. Unless stated otherwise all specifications are measured at fundamental wavelength and maximum pulse repetition rate. The parameters marked typical are not specifications. They are indications of typical performance and will vary with each unit we manufacture.
2）Factory-set pulse repetition rate is fixed at max repetition rate shown in the table. Smoothly variable pulse repetition rate is possible when laser is externally triggered. In internal triggering mode repetition rate can be divided by integer number down to f/2, f/3, f/4,.. 1 Hz.
3）At FWHM level at fundamental wavelength, measured with 350 ps rise time photodiode.
4）Pulse energies for harmonic wavelengths are maximum possible values available from H1 series harmonic generator module. See datasheets of H1 for details.
5）Measured during 30 seconds operation after warm-up.
6）Over 8 hour period after 20 minutes of warm-up when ambient temperature variation is less than ±2 °C.
7）Full angle measured at the 4σ level.
8）Peak to peak value, measured for 30 seconds of operation after laser warm up.
9）Beam diameter is measured 20 cm from laser output at the 4σ level.
10）In respect to falling edge of pump diode triggering pulse.
11）Motorized attenuator intended to be attached to the laser housing. Transmission can be changed remotely trough laser web-server control interface.
12）Power adapter dimensions might differ from indicated here, depending on model.
13）Q1 laser is compatible all models of stand-alone H1 harmonics generator. Please refer to harmonic generator datasheets for detailed specifications.
